The Daines Medical Dynasty

The Daines Medical Dynasty

Joseph Daines BS’68
Michael Daines BS’99   
Brad Daines BA’05

The School of Biological Sciences claims all of our alumni, but sometimes there’s a kind of harmonic convergence that elevates an entire family of U biologists into the spotlight.

Such is the case with the Idaho Daines Family of orthopedic surgeons—Joseph “Pete,”,BS’68; Michael, BS’99; and Brad, BS’05—a virtual dynasty in orthopedic surgery. Brian, who as an undergraduate attended BYU (the U’s traditional rival to the south) also practices orthopedics but in Arizona. The oldest son Gordon was the outlier. He found his passion in history and is now a university archivist with a doctorate in education.

The University of Utah Daines Dynasty goes back three generations, beginning in 1920 when the grandfather of Pete’s wife Susan--also mother to his sons--attended undergraduate school at the U and then went on to medical school in New York City, ultimately returning to the west to start a general medical practice in Preston.

Michael Daines, MD

Born in 1945, Pete was at first a math major at the U but changed to biology/pre-med before attending Columbia Medical School followed by an orthopedic residency at George Washington University. His father, who died a year after Pete’s return to Idaho in 1979, also practiced orthopedics in Boise.

Years later Pete’s son Michael would also graduate from the U and head east to medical school at Columbia College of Physicians and Surgeons, followed by a residency in orthopedics at the University of Iowa. Later he was awarded a fellowship to Oxford University to study shoulder surgery for a year. He now specializes in shoulder surgery in addition to general orthopedic surgery at West Idaho Orthopedics near Boise, where he and his siblings grew up.

Not to be outdone by his older brothers, Brad entered medical school at the University of Washington following his graduation from the School of Biological Sciences. Subsequently, he completed a residency at the University of Vermont in orthopedic surgery followed by fellowship training in total joint replacement at the Hospital for Special Surgery/Cornell University. Brad focuses on hip and knee replacement which can include robotics.

For the first few years in practice, his father Pete was his assistant in the operating room. “I ended up not really quitting totally, from practice until 2018,” Pete says. In addition to assisting Brad, he provided medical evaluations for insurance companies, conducted independent exams and wrote up patient histories and reports for attorneys. "To have my dad with me has been an awesome experience” Brad said in a 2016 KBOI 2News story “because he is sort of a calming presence."

"How does it feel seeing three of your four boys following in your footsteps?" the reporter asked Pete in the same story. "Well,” said the patriarch, “it's sort of an ego trip, but I think it's great. I just wanted my sons to do something that they enjoyed." Says Brad, "Like my brothers, I always thought I was going to be a doctor. I didn't ever feel any pressure, but I noticed that my dad liked his job."

Clearly orthopedics is in the Daines Family blood, and clearly the University of Utah’s Biology Department--now the School of Biological Sciences--played a role in the family’s success.

Both Michael and Brad remember the invaluable experience they had in the Biology Undergraduate Research Program (BioURP) with Rosemary Gray, now an emerita faculty. Michael was a research assistant with Sandy Parkinson while Brad found a research mentor in Dave Carrier. “I learned a lot from him about the scientific method,” says Brad. “In addition, because his work did involve animal subjects, I learned much about the balance of the ethical treatment of animals and the need for scientific advancement. We worked with canine subjects, and the length to which he went to ensure good care of these animals was impressive.”

Brad Daines, MD and two future U Biology Alumni

Additionally, Brad really found his groove in the honors program and his upper level biology classes were also an incredible experience, particularly, he remembers, comparative vertebral morphology. Membership in the University Chorus and Sigma Chi fraternity gave him a musical and social outlet.

Both brothers recall the “incredible athletic programs” at the U which gave them a reprieve from the lab and the classroom. Along with sports, there was a love of the mountains and skiing. The combination of the Daines family legacy, recreational opportunities and the academic reputation of the U would converge for a memorable experience for both.

Michael’s research experience in the Parkinson lab was a segue for Columbia Medical, his father’s alma mater. While in New York City, Michael had the singular experience of living through the attacks on the World Trade Center on September 11, 2001. Later, during his Oxford fellowship in the UK, he also worked on several research projects related to the shoulder.

An avid hunter, fisherman and triathlete, Michael enjoys spending time with his three kids, along with his hunting dog “Hawkeye.”

For all of the Daines, there have, of course, been challenges due to the current pandemic, including for Brian in Arizona who, his father remarks, finds himself overworked, doing “everything” related to joint medicine in a small clinic.

“I traveled a lot with my wife,” says Pete, remembering pre-COVID-19 times when he floated European rivers through places like Budapest and Vienna, sometimes through spectacular tunnels 30 miles long. A music enthusiast, he also sang bass in a choir and for five years sat on the board of the Boise Philharmonic. Along with Michael Brad also loves to fish and with his father enjoys music, opera in particular.

While the pandemic has slowed these activities, it has consorted to bring the family, which now includes thirteen grandchildren, closer together. Clearly the spread of the coronavirus has impacted the Daines and their respective medical practices just as it did Pete’s early relatives during the 1918 flu pandemic. “It was a bad pandemic as well,” Pete says, referencing family letters left behind, but “nothing like this one. [Back then] they lost family, this, that and the other thing. It took two years to get past it. That’s what it does. It comes and turns your life upside down.” Even so, he says, the earlier pandemic didn’t keep people out of work as much as the current one.

Says Michael, “I have had to navigate the need to care for patients and also keep my office staff safe. As a small business owner, we have had to find creative solutions to keep people working and keep the doors open.” Brad, too, has had to make the adjustments to the way he works.  “Life is always uncertain,” he says, referring to the past year. His advice? “Remain flexible and do the best you can every day. Embrace the fact that life will take you down unexpected paths. Upon reflection, many of the best things in my life happened when my plan deviated.”

Michael agrees: “Take your opportunities when they come up and have no fear!”

Will the Daines tradition of orthopedic surgery carry on into the next generation? “I think there’s going to be some of my grandkids going into medicine,” says Pete. “It probably isn’t going to be the conglomeration [of a medical life] like I got. I don’t know how that happened,” he quips, referring to three-fourths of his progeny who are surgeons.

“They just wanted to go and they did. Back then I could take my kids into the operating room with proper supervision and they could watch things. You can’t do that now. It’s not allowed. I had that opportunity to have some stuff in the operating room and I think that cemented for them going into medicine…. I didn’t mean for them to all become doctors, but that’s what happened. I’m very proud of them.”

As for Brad, his children are still too young (7 and 5) to have shown any interest in a career in medicine-- yet."

David Hillyard

David HillyARD

 

 

When David Hillyard, BS’73, was recognized in November with a Healthcare Hero Award, he was quick to share the love. “This honor should really go to the fantastic team of individuals I’ve been working with who have made high-capacity, quality COVID testing possible,” Hillyard said. “It’s very flattering, but every day I just think about the critical contributions front-line laboratory workers make for this effort every day.”

The sentiment is typical of the collaborative and generous nature of the Professor of Pathology at the University of Utah School of Medicine and founding Director of Molecular Infectious Disease Testing at ARUP, the largest academic laboratory in the country.

“This year, Utah’s healthcare leaders went above and beyond, pivoting their time, creativity, ingenuity, and magnanimity to face off against a global pandemic,” read the Utah Business citation. “This is only the beginning of our nation’s battle against COVID-19 … and we are so grateful to these warriors for leading the charge.”

Hillyard’s interest in the U started with a love of Ute basketball in the era of its legendary coach Jack Gardner, known as “the Fox,” who shepherded five All Americans, including Billy “The Hill” McGill.

“In high school, I visited the U for hosted debate and drama competitions and got a glimpse of its campus. I never thought I could afford to go out-of-state for college and saved all of my earnings … to be able to pay for at least a first year at the U.”  Scores of lawn mowings later and he had tuition which at that time was $175 per quarter. “I also had the academic blessing,” he says,“ of my Uncle Charlie, a renowned nuclear physicist, who received his PhD at the U and gave the science departments a high rating.”

Hillyard’s acceptance to the U was transformative for the Ogden native whose “first rate education” in biology and chemistry was elevated by the extraordinary opportunity to participate in basic research beginning his sophomore year. Professor K. Gordon Lark would arrive during Hillyard’s sojourn in the Department of Biology, now the School of Biological Sciences, and the legendary chair, who passed away in April, turbo-charged the department with newly recruited faculty of outstanding molecular biologists and distinguished visiting professors.

The expanding breadth and rigor of the department was an accelerant to Hillyard, allowing for him graduate level exposure to biology as an undergraduate but most importantly, he says, personal mentoring in bioresearch in “a thrillingly fun environment. Without question, these short years were the foundation for a happy career and any professional successes to come.”

As an undergraduate in Dr. Baldomero “Toto” Olivera’s lab, he worked on differences in pathways and magnitude of turnover of the metabolic cofactor NAD in e. colio and Hela cells.  “My fondest memories of my time at the U are informal dinner parties with lab mates and visiting scientists at the home of [Toto]” he recalls, adding that the “[l]ate night jaunts with Toto to the Roadway Inn for apple pie ala mode and experiment planning rank way up there too.” Many would agree with him that Olivera’s mentoring of undergraduates at the U is legendary.

Later, with the advent of polymerase chain reaction (PCR), a kind of molecular photocopying now commonly used in biology labs, Hillyard collaborated with Olivera on the identification and cloning of conopeptide genes from venomous marine snails, groundbreaking work that has since been widely celebrated as a potential replacement for opioids and their vaulting addictive properties. “As a clinical pathologist,” says Hillyard, “my work has focused on molecular infectious disease test development and the clinical application of these tests.”

Following graduation from the U, Hillyard pursued medical training at Columbia University’s College of Physicians and Surgeons in New York City along with fellowship training in pathology. He then returned to the U for fellowship training in microbial genetics and medical microbiology followed by a position as assistant investigator with the Howard Hughes Medical Institute at the U’s School of Medicine. He also joined the faculty of the Department of Pathology.

Hillyard figured prominently in establishing a test to meet the nationwide demand for diagnosing COVID-19. Beginning in January he and researchers at ARUP validated one of the first high-throughput diagnostic COVID-19 tests in the nation. With Emergency Use Authorization from the U.S. Food and Drug Administration in late February 2020, Hillyard and his team worked around the clock to ensure they had a test ready to launch in March with a turnaround time of less than two weeks.

More recently Hillyard and his team have worked on developing co-tests for Covid-19/Flu AB/ and respiratory syncytial virus. “The scale and urgency of the project has certainly been challenging and a bit life changing,” he confesses, “but is dwarfed by the positive experiences of working with teams of dedicated laboratorians stepping up to the plate with their hard work, problem-solving, and commitment to do good.”

“There are so many surprises with COVID-19 that you’re never fully prepared, no matter how ready you think you are,” said Hillyard in the Utah Business profile in November, as he described preparing for flu season with cases continuing to rise. “The flu season hasn’t been very bad in the southern hemisphere this year, perhaps because of physical distancing and other measures taken to mitigate COVID-19 spread, but the flu will come.”

The good doctor’s COVID-19 research has been in collaboration with Boston-based Ginkgo Bioworks whose co-founder Reshma Shetty is another celebrated alum of the Olivera lab. Together with other government and non-profit health organizations they’ve studied the genetics of the virus in Utah and analyzed how its molecular makeup is evolving. The consortium has also conducted a major study comparing testing accuracy across different labs and instrument platforms.

No doubt the pandemic has been a singular time for all of us, but being on the frontlines of infectious disease testing has put a megaphone on all of it for Hillyard. Beyond family, he takes refuge in bicycling, especially hill climb racing. “I also love hiking, photography and as a wellness advocate for my department, [I] enjoy keeping up on the latest in food science. Unfortunately," he admits, "I’m a terrible cook."

Terrible in the kitchen or not, in his typical generous fashion Hillyard is quick to offer thoughtful advice to the next generation of scientists and health professionals. “[T]rain broadly, recognizing the importance of multiple skill sets for a successful career,” he says. “I would also suggest seeking out the best mentors at the best institutions in an environment where you can build personal relationships and also have fun.”

Dr. David Hillyard is a model U Biology alumni, transforming his immersion in undergraduate research with star, engaged faculty to a most elevated and award-winning legacy underscored by public service.

Uncle Charlie, it turns out, was right.

COVID Connections

Creating a Virtual Symposium


Tanya Vickers

Rising to the Challenge

Science is about preparing the next generation of innovators, explorers, and connoisseurs of curiosity. For the last 29 years the College of Science ACCESS program has been the “first step” on this journey of discovery. The ACCESS program runs from June to August and is open only to first-year students freshmen and transfers).

A cornerstone of the ACCESS experience is the opportunity for the student cohort to share their work with faculty and peers during a research poster symposium. The symposium is a powerful learning experience that mirrors professional science conferences and a career in the field, and plays a key role in the program.

When COVID-19 hit the U.S., the longstanding tradition of the Spring Research Symposium was in jeopardy. As the director of ACCESS , I was driven to find a way to continue the capstone symposium, and provide talented first-year student scientists the opportunity to showcase their research, in spite of social distancing.

With just six weeks until the event we decided to design, build, and launch a novel virtual research symposium platform. The sudden shift and short time-frame presented a real challenge, but it was also an opportunity to pursue and explore innovative approaches to current standards that, if not for CO VID-19, would have been stagnant.

It’s been six months since the Virtual Symposium, and we are still surprised by its success. The merits and results of the virtual platform challenged the notion that in-person is best. The in-person symposium normally saw about 200 guests. In contrast, the virtual symposium reeled in nearly 6,000-page views in three days and 260 guests attended the live zoom presentations.

Thinking Differently

COVID-19 upended and reshaped our everyday lives and challenged everyone to find new approaches to routine activities and novel fixes for nascent problems, much like scientists do on a regular basis.

When the on-campus student research experience was cut short in March, it didn’t mark the end of learning for the 2019-2020 ACCESS cohort. Research faculty agreed to continue mentoring remotely, which included helping the students report their research in a scientific poster they would present virtually. Unfortunately, the technology for a virtual research poster presentation did not exist.

That’s when I began the process of envisioning and creating the Virtual Symposium platform, as it’s now known. I started with identifying the critical elements of an in-person research symposium and considering how to transpose them to a virtual model. My experience teaching and using Canvas (used to deliver course content) shaped the content, and with the collaboration and support of Micah Murdock, Associate Director of Teaching and Learning Technologists (TLT ), a novel virtual research symposium was fully realized.

Embracing Technology

The platform was a lofty goal that required three defining features: a webpage for students to introduce their project, a message board for peers, guests, and mentors to pose questions, and a live Zoom presentation with question and answer.

Each student had a personal webpage that included their research poster, a 3-minute video summary of their research project, and a short personal bio. These elements provided guests with an introduction and interactions analogous to an in-person symposium.

In-person symposia can feel rushed, but the virtual platform offered the advantage of providing guests more time to preview projects on their own, before using one, or both, forum tools—the student scientist’s discussion board, or the 30-minute Zoom live session scheduled on the last day—to ask questions or comment.

Building For the Future

Throughout this process, we wanted to build a tool with the future, as well as other disciplines and applications, in mind. We are proud to announce that the platform has already seen use for the School of Biological Sciences Virtual Retreat, ACCESS Alumni Career Panel, and a number of campus-wide projects. Most recently, the Virtual Symposium was chosen to serve as the cornerstone of the new College of Science high school outreach platform SCIENCE NO W—engaging students, presenters, and elite scientists from across the U.S. and around the world.

As a species and as scientists, we always look forward to new ideas and what can be done. In our darkest hours, we find a space for new forms of unity and growth, and can challenge ourselves to create and expand. CO VID has been undeniably difficult, but the development of new platforms and technologies, like the Virtual Research Symposium, show that sometimes, when we are forced to make changes to long held traditions, the outcome goes beyond finding an equivalent, making what we thought was “best” even better.

Special thanks to Dean Peter Trapa, ACCESS Program Manager, Samantha Shaw, and to the ACCESS students and mentors for believing in the vision of a Virtual Research Symposium.

Giant Poisonous Rats

The secret social lives of giant poisonous rats.

The African crested rat (Lophiomys imhausi) is hardly the continent’s most fearsome-looking creature—the rabbit-sized rodent resembles a gray puffball crossed with a skunk—yet its fur is packed with a poison so lethal it can fell an elephant and just a few milligrams can kill a human. In a Journal of Mammology paper published today, Smithsonian Conservation Biology Institute, University of Utah and National Museums of Kenya researchers found the African crested rat is the only mammal known to sequester plant toxins for chemical defense and uncovered an unexpected social life—the rats appear to be monogamous and may even form small family units with their offspring.

Sara B. Weinstein and Katrina Nyawira.

“It’s considered a ‘black box’ of a rodent,” said Sara Weinstein, lead author and Smithsonian-Mpala postdoctoral fellow  and postdoctoral researcher at the University of Utah. “We initially wanted to confirm the toxin sequestration behavior was real and along the way discovered something completely unknown about social behavior. Our findings have conservation implications for this mysterious and elusive rat.”

People in East Africa have long suspected the rat to be poisonous. A 2011 paper proposed these large rodents sequester toxins from the poison arrow tree (Acokanthera schimperi). A source of traditional arrow poisons, Acokanthera contains cardenolides, compounds similar to those found in monarch butterflies, cane toads and some human heart medications. Cardenolides, particularly the ones in Acokanthera, are highly toxic to most animals.

“The initial 2011 study observed this behavior in only a single individual. A main goal of our study was to determine how common this exceptional behavior was,” said co-author Denise Dearing from the University of Utah.

When threatened, the African crested rat lives up to its name and erects a crest of hair on its back to reveal a warning on its flanks—black and white stripes running from neck-to-tail on each side of its body. The 2011 study hypothesized that the rats chew the Acokanthera bark and lick the plant toxins into specialized hairs at the center of these stripes.

In the new study, researchers trapped 25 African crested rats, the largest sample size of the species ever trapped. Using motion-activated cameras, they documented nearly 1,000 hours of rat behavior. For the first time, they recorded multiple rats sequestering Acokanthera toxins and discovered many traits that suggest they are social, and likely monogamous.

“Everyone thought it was a solitary animal. I’ve been researching this rat for more than ten years, so you would expect there to be fewer surprises,” said Bernard Agwanda, curator of Mammals at the Museums of Kenya, co-author of this study and the 2011 paper. “This can carry over into conservation policy.”

A rich social life

As a postdoctoral fellow at the Mpala Research Centre, Weinstein first searched for the rats with camera traps, but found that they rarely triggered the cameras. Weinstein was then joined by Katrina Nyawira, the paper’s second author and now a graduate student at Oxford Brookes University. Together, they spent months experimenting with live traps to capture the elusive rodents.

“We talked to rangers and ranchers to ask whether they’d seen anything.” said Nyawira. Eventually they figured out that loading the traps with smelly foods like fish, peanut butter and vanilla, did the trick. “Out of 30 traps, we finally got two animals. That was a win. This thing is really rare.”

Those two animals changed the course of the study. They first caught an individual female, then caught a male at the same site two days later.

The African crested rat.

“We put these two rats together in the enclosure and they started purring and grooming each other. Which was a big surprise, since everyone we talked to thought that they were solitary,” Weinstein said. “I realized that we had a chance to study their social interactions.”

Weinstein and Nyawira transformed an abandoned cow shed into a research station, constructing stalls equipped with ladders and nest boxes to simulate their habitat in tree cavities. They placed cameras in strategic spots of each pen and then analyzed every second of their footage, tracking the total activity, movement and feeding behavior. The aim was to build a baseline of normal behavior before testing whether behavior changed after the rats chewed the toxin cardenolides from the poison arrow tree.

“They’re herbivores, essentially rat-shaped little cows,” Weinstein said. “They spend a lot of time eating, but we also see them walk around, mate, groom, climb up the walls, sleep in the nest box.”

The footage and behavioral observations strongly support a monogamous lifestyle. They share many of the traits common among monogamous animals: large size, a long life span and a slow reproductive rate. Additionally, the researchers trapped a few large juveniles in the same location as adult pairs, suggesting that offspring spend an extended period of time with their parents. In the pens, the paired rats spent more than half of their time near each other, and frequently followed each other around. The researchers also recorded special squeaks, purrs and other communicative noises making up a wide vocal repertoire. Further behavioral studies and field observation would uncover more insights into their reproductive and family life.

After the researchers established a baseline of behavior, they offered rats branches from the poison arrow tree. Although rats did not sequester every time the plant was offered, 10 rats did at least once. They chewed it, mixed it with spit, and licked and chewed it into their specialized hairs. Exposure to the Acokanthera toxins did not alter rat behavior, and neither did eating milkweed, the same cardenolide-enriched plant used as chemical defense by monarch butterflies. Combined, these observations suggest that crested rats are uniquely resistant to these toxins.

“Most people think that it was a myth because of the potency of the tree,” said Nyawira. “But we caught it on video! It was very crazy.”

The rats were selective about using Acokanthera cardenolides, suggesting that rats may be picky about their toxin source, or that anointed toxins remain potent on the fur a long time, just like traditional arrow poisons from the same source.

African crested rat conservation

The African crested rat is listed as IUCN species of least concern, but there’s little actual data on the animals. Agwanda has studied African crested rats for more than a decade—and sees indications that they’re in trouble.

“We don’t have accurate numbers, but we have inferences. There was a time in Nairobi when cars would hit them and there was roadkill everywhere,” said Agwanda, who continues to monitor the populations. “Now encountering them is difficult. Our trapping rate is low. Their population is declining.”

The research team is planning future studies to better understand their physiology and behavior. “We are particularly interested in exploring the genetic mechanisms that allow the crested rats and their parasites to withstand the toxic cardenolides” said co-author Jesús Maldonado of the Smithsonian Conservation Biology Institute and Weinstein’s Smithsonian-Mpala Postdoctoral fellowship co-advisor.

“We are looking at a broad range of questions influenced by habitat change. Humans have cleared forests to make farms and roads. We need to understand how that impacts their survival,” Agwanda said. Additionally, Agwanda is building an exhibit at the Museums of Kenya to raise awareness about this unique poisonous animal.

James Detling

James K. Detling

 

 

James K. Detling (PhD’69) arrived at the University of Utah from Ohio State University where he had just finished his Master’s degree in botany. He followed his graduate advisor, Dr. Lionel Klikoff, who transferred to the U as a tenure-line faculty member. While his advisor guided Detling’s research and mentored him in the ways of becoming a university faculty member, “perhaps my fondest memories are of Dr. Kimball Harper,” he says. Detling’s PhD research involved a study of physiological ecology of saline-tolerant halophytes in the salt deserts west of Salt Lake City. Of Harper, Detling says, “He always graciously shared his vast knowledge of the ecology of Utah’s various ecosystems, and made himself available to answer questions or discuss ideas. Imagine my disappointment,” he says somewhat cheekily, when several years later he learned that Harper had left the U to join the faculty at the Ute’s traditional rival located south of Salt Lake City: Brigham Young University.

In Utah, Detling enjoyed exploring the mountains and deserts, “first to scout out potential field sites for my research in plant ecology,” he says “and then to explore the fabulous outdoor recreational opportunities they provided.” After teaching at the U for one year as a replacement for Harper who went on sabbatical, he taught at a private liberal arts college in Ohio for five years. Following that, in 1975, he returned to the west, to Colorado State University where he remained on the faculty until his retirement in 2010.

In Fort Collins his professional activities included the study of biotic and abiotic factors affecting both structure and function of grassland ecosystems. On the editorial board of the journal Frontiers in Ecology and the Environment, the Berkeley California native was also elected Fellow of The American Association for the Advancement of Science. Additionally, he was also designated an ISI Highly cited researcher.

In the 80s Detling retreated to the field of the mixed-grass prairie at Wind Cave National Park in South Dakota. There he studied and reported on how black-tailed prairie dogs create habitat patches characterized by altered species composition, lower standing crops of plants, but also higher forage quality. “Native wildlife species such as bison, pronghorn, and elk preferentially feed on these prairie dog colonies and likely derive nutritional benefits from doing so,” he reported. Findings supported his hypothesis that genetically-based morphological and physiological differentiation had occurred in several native grass species as a result of strong selection pressures from grazing mammals on prairie dog colonies.

A decade later he turned his attention to “Grassland Vegetation Changes and Nocturnal Global Warming,” resulting in a  paper of the same title co-authored by Richard D. Alward and Daniel G. Michunas published in Science.

Since retirement Detling has continued research on grassland ecology with former students and colleagues. He has also turned from the study of one kind of grassland to another--the golf course—which has come in handy since the advent of the coronavirus pandemic has curtailed other beloved activities: traveling and dining out.

Sonia Sehgal

Sonia Sehgal

 

U Biology's Sonja Sehgal accepted a Beckman Scholarship this past spring to add to the trove of awards that were already sitting on her academic “mantle” at home. Collective kudos include a Biology Research Scholars Award, a College of Science Scholarship and a Utah Flagship Scholarship.

The Beckman, however, is a step up from her other awards. It represents an unprecedented opportunity, perhaps found nowhere else, in which an undergraduate researcher can hone her craft at the bench and under extraordinary mentorship. The program is a 15-month, mentored research experience for exceptional undergraduate students in chemical and biological sciences, and Martin Horvath, associate professor in the School of Biological Sciences, will serve as her mentor. (Rory Weeks, undergraduate in the Department of Chemistry is the second U Beckman Scholar for 2020-21.) Each scholar receives a $21,000 research stipend to facilitate nine academic calendar months and two three-month summers of research experience. Recipients from around the nation participate in the prestigious Beckman Symposium each summer with one another. Their research began in June 2020 and will conclude in August 2021.

“I started out as a freshman in the ACCESS,” the biology senior explains, referring to the decades-long program hosted by the College of Science Program for Women in Math and Science. “Through this program, I was able to explore various fields in STEM which really kick-started my interest in pursuing biology! Joining the Horvath Lab further sparked my curiosity and has shown me that science goes beyond the stereotypical image of a “scientist.”

Tracking toward a career in medicine

Sonia Sehgal (undergraduate, Biology Research Scholar, Beckman Research Scholar) and Martin Horvath discuss the structure of MutY

Sonia Sehgal (undergraduate, Biology Research Scholar, Beckman Research Scholar) and Martin Horvath discuss the structure of MutY.

Sehgal is far from stereotypical, as a scientist or as an undergraduate. As a woman she knows that she’s in the minority as she works through her academic career and finally a professional career in STEM (Science Technology Engineering and Mathematics). As a complement to her academic career, the Sandy, Utah native has found a job as a University Ambassador. “The ambassadors work closely with the Office of Admissions to share our experience and bring a personal perspective to prospective U of U students,” she says. “When not giving tours or working recruitment events, we can be found having a good time with each other or,” she quips, “practicing walking backwards.”

Though Sehgal finds herself walking backwards while giving tours, she is definitely moving forward in her academic career. “I’m excited to continue doing research and I also plan on attending medical school after graduation. I want to learn about the various mechanisms that can cause diseases to present themselves in different forms across individuals. I want to use this platform to relay these findings with patients and create more representation in the field to strive for a more trusting and effective patient interaction.”

But before medical school, there’s research to be done, a focus in undergraduate education in the SBS that has arguably become the School’s signature.  “In the Horvath lab,” Sehgal explains about her work, MUTYH is a DNA repair enzyme commonly related to diseases like cancer. I am currently finding the role of different biological probes to see how they can affect the activity of this enzyme. Learning more about regulating the activity of MUTYH will allow us to create better drug-targeting systems for cancer in the future.” What most people, even the scientifically-inclined, may not know about the model subject Sehgal is studying is that the MutY enzyme can be found in almost every living organism, yet there is still a lot we don’t know about it.

Hangin' out.

That’s something that inspires rather than discourages Sehgal who will graduate with her BS in 2021. With the help of the Beckman Scholarship, the mentorship of Horvath and the broad view of higher education she gets by being an ambassador, Sehgal finds her future as she tracks toward a career in medicine, promising. And true of all of accomplished undergraduate researchers of Sehgal’s stripe, she is poised for far more awards, and accomplishments.

“The Beckman experience has been going well,” she reports. “Because of the COVID-19 pandemic, the first stage has been virtual. I have been working on coding and molecular docking. However, I look forward to getting into the lab next semester and start testing!” Of Sehgal Horvath adds, "Sonia has a gift for finding a simple clear question to address in her science. She will go far. I feel really lucky to have had the chance to work with her these past years."

Asked what her interests and “likes” she doesn’t stray very far from her time in the lab. She likes rock climbing, dogs … and getting positive results for polymerase chain reaction (PCR), a method widely used to rapidly make millions to billions of copies of a specific DNA sample.

It’s the sort of thrill that allows a budding scientist, like Sonia Sehgal, to take a very small sample of DNA and amplify it to a large enough amount to study in detail.

Beckman Abstract

  • "Finding the role of biological probes on MUTYH activity,"(S. Sehgal)
    DNA damage is implicated in many cancers, such as colorectal cancer. One form of this damage occurs when guanine becomes oxidized to form 8-oxoguanine (OG). MUTYH is a base excision repair (BER) enzyme in humans that excises adenine (A) at OG:A lesions in DNA and thus prevents mutations that may arise after rounds of replication. Interestingly, both inhibition and overactivation of MUTYH can contribute to cancer-causing activity. In this project, MUTYH will be studied through computational modeling and an activity assay to find biological probes that can bind to the protein and affect its function. These probes can later be tested in animal models and may serve as the foundation for anticancer drug discovery. In addition, through analyzing the effect of biological probes on this enzyme, the BER pathway and the dual role of MUTYH in preventing and causing cancer can be further understood. Use of these probes to control MUTYH activity and BER overall can aid with creating more efficient drug targeting systems for cancer treatment in the future.

Amy Davis

“I enjoy learning about how infectious diseases have shaped human history because I find it inspiring to frame my current work in a broad historical context,” says Amy Davis, PhD’03.

A Senior Director, Biochemistry Research & Innovation at Utah-based BioFire Diagnostics, LLC, Davis says she was “fortunate to be born into a world with antibiotics and large-scale vaccine production,” while reminding us that “these tools in humanity’s struggle against microbial pathogens have only been around for the last 70-80 years.”

With her work at BioFire whose systems have become the new standard for syndromic infectious disease diagnostics, what she calls her “obsession” with the history of medical science could not have converged at a more timely, and daunting, time. The coronavirus pandemic in the United States is currently emerging in a scorching third wave, and there is a herculean effort underway to bring a vaccine to market. This, of course, will require accelerated and accurate diagnostics, something BioFire’s co-founder Randy Rasmussen, also a PhD alumnus (’98) from the School of Biological Sciences, recently reiterated during a virtual COVID Salon sponsored by SBS in May of this year.

Davis, who earned her BS in biology with honors from Penn State, followed by a year as a Fulbright Scholar, recalls what first drew her to graduate school at the SBS. It was the “fabulous faculty, collaborative culture,” and, of course, the spectacular mountain setting. “My graduate education at the University of Utah taught me how to think critically, work diligently, shake off setbacks, and thrive on the pursuit of understanding,” she says. “I loved everything from the journal clubs to late nights in a quiet lab dissecting tetrads to ‘TA-ing’ for Joe Dickinson's Genetics course to planning the next experiment.”

She remembers that seeing the mitochondrial net phenotype for the first time in a yeast mutant she had isolated in a genetic screen was “pretty exciting!” She also remembers fondly Professor Janet Shaw. While studying the molecular mechanisms of mitochondrial dynamics in Shaw’s lab, Davis was taught by her “amazing mentor and friend…how to ask the right questions, how to write, how to present, and how to balance.”

That training, experience and mentoring have served Davis well. Following her graduation from SBS, she did a post-doc on the other side of the Rockies--at the University of Colorado, Boulder. There she was at the bench researching the biology of the yeast telomerase RNA, an essential core component of the telomerase ribonucleoprotein (RNP) enzyme that synthesizes telomeric sequences onto chromosome ends.

The call of the Wasatch Front, however, as well as that of the U’s Brain Institute, propelled Davis in 2007 back to Salt Lake City where she was manager and then associate director at the Institute for a total of six years. Following that she moved to the U’s Medical School for a two-year stint to help establish a research program development office.

A career in what’s been called “The Century of Biology,” especially as it relates to health, can take one on a circuitous route. Davis’ has been no exception. After spending 20 years in academic environments, Davis made the leap to work in industry. At BioFire she learned to work with dozens of complementary teams to translate research ideas in robust clinical diagnostic tools. To broaden her experience in the biotech space, Davis accepted a role at the start up IDbyDNA as VP of Operations. The company, also located in the U’s Research Park with BioFire, works in metagenomics technology to simultaneously profile tens of thousands of microorganisms and pathogens in any sample.

Emblematic of the extraordinary synergy Research Park was designed for, companies like BioFire and the newer IDbyDNA create opportunities for not only advancing medical technology but the careers of many University of Utah alumni. Davis later returned to BioFire as a Senior Director in research and development, where she is enjoying applying the perspective gained from operations roles to early-stage innovation projects.

To date, no other company has FDA-cleared and CE-IVD (European Union-cleared) marked assays for more pathogens than BioFire. Again, the timing of the company’s ascendancy has proven auspicious.

In the kitchen with the whole fam dam.

“As we are learning from COVID,” says Davis, “emerging pathogens (and emerging antimicrobial resistance of old pathogens) can challenge societies in significant ways. …The more we learn about the patterns of infectious diseases and human efforts to understand and combat their microscopic agents, the better we can prepare for present and future threats.”

While COVID has focused global attention on the threat of emerging viral respiratory pathogens, she says she hopes that this “reality check bolsters efforts to combat emerging antimicrobial resistance in pathogens that have been with us for centuries.”

Meanwhile, Davis continually returns to her passion for the history of medicine. She finds that her reading deeply informs her intense career at BioFire, providing perspective, inspiration and context for their work. And what exactly is on her bedside reading stand? The Mosquito by Timothy C. Winegard; the portentous sounding Superbugs: The Race to Stop an Epidemic by Matt McCarthy; and Microbe Hunters by Paul de Kruif.

From these historical tomes she is happy to base her advice to new graduates of the School of Biological Sciences, particularly telling during this pandemic time: “Take the long view and train for a career that will fulfill you ten, twenty, thirty, forty years from now.”

Dale C. Larsen

Dale C. LARSEN


In the mid-1950s, when Dale C. Larsen (BS’59) first enrolled at the U there were only six Colleges on campus including the College of Letters and Science, and a two-year medical school.

Larsen was born and raised in Roosevelt, Utah, a small farming town in northeastern Utah. The drive to Salt Lake City in those days was long and tedious, often on dirt roads and narrow two-lane highways. 

But Larsen had a goal in mind. He wanted to earn a degree at the U and get into dental school. 

“I knew several people who attended the U and liked the idea of doing so myself,” he recalls. He knew a degree in biology or medical biology would ensure access to dental schools. 

After high school, Larsen first served in the Navy in Korea.  “During the Korean war I was an aviation aerial photographer in an air squadron. Around airplanes and in them a lot. I flew from three different aircraft carriers,” he says. 

When the war ended in 1953, Larsen returned to Utah and started attending the U.

“I lived in a basement apartment one block off-campus until I met my wife, Joni. After we got married, we lived in an apartment on about 1400 South and 200 East,” he says. (Today, that location is near Liberty Park.)
 
In high school and for a few years afterward, Larsen played saxophone in a Big Band dance orchestra. "The wife of the leader of the orchestra had a sister named Joni and I met her then and we were married in 1956,” he recalls. 
 

At the U, Larsen’s favorite professor was Stephen D. Durrant, who was an expert in vertebrate zoology and mammalian anatomy. "Durrant’s class on mammalogy was among the best courses I had in school,” says Larsen.

Larsen earned a bachelor of science degree, in Biology, in 1959 and promptly enrolled in dental school at Washington University in Saint Louis, Missouri. He later moved back to Roosevelt, Utah, and held a private dental practice for 47 years. 


He and Joni had four children: Trudi, Troy, Todd, and Trent.                       

"Our oldest son, Troy, attended the U for one year and the youngest son attended a physical therapy program run by the University a number of years ago,” he says. Joni passed away in 2013.

Dr. Larsen, aerial photographer, Korean War

Larsen has enjoyed a life-long passion for aviation.

"I became interested in aviation as a child when I saw neighbor boys flying their model airplanes. Then in the Navy I was an aviation photographer. After coming home (from Korea) I got my private pilot’s license in 1958. Still flying now after 62 years,” he says.  
 
Larsen’s best advice for students is, “get a good education and stick to your goals.

Jason Allen

Jason Allen knew early on of the opportunities the state’s flagship research university could offer him just an hour north of where he grew up in Springville.

“I had always wanted to attend the University of Utah due to its prestige within the state and nationally,” he says, especially due to the U’s stellar reputation in science and technology.

He wasn’t disappointed. Now a Physician and Medical Director of the Breast Imaging section in the University of Colorado Health South Region, this doctor of osteopathic medicine (DO) cut his teeth as a researcher in Dr. David Stillman’s lab with Dr. Leena Bhoite. “It was in his lab that I got great exposure to real ‘at the bench’ lab work as well as all the frustrations and excitement that go along with it,” he says.

Working in the Bioscience Undergraduate Research Program (BioURP) at the U was also formative for Allen, including the introductory summer course which he counts as “a great introduction to the program overall, [to] new people and some of the intricacies of basic … lab work.” He especially enjoyed working with Dr. Rosemary Gray and Dr. Janet Shaw, both of whom were “great mentors and significantly helped cultivate my interest in learning about the biological sciences.”

Additionally, the spring undergraduate research symposium “amply prepared me for the requirements of medical school, internship and [a] residency, and even now working in the field of medicine,” he recalls. It wasn’t just the technical know-how and scientific rigor of BIOURP that propelled him forward into his career; the public speaking requirements and likely the network were also useful to him as he prepared for professional school.

After graduating from Kansas City University of Medicine and Biosciences in 2005, Allen completed a residency in Radiology with the San Antonio Uniformed Services Health Education Consortium in 2010. Following that he began a career in the United States Air Force at David Grant Medical Center as a general radiologist teaching radiology residents. After four years there and nine years of active duty service, he separated from the Air Force and completed fellowship training with the University of California at Davis Hospital in Sacramento.

In the Centennial State Allen is the lead interpreting physician in the breast imaging section. “Our group provides radiology interpretation services and image guided interventions for the University of Colorado Health system, as well as a number of additional smaller hospitals in southern Colorado,” he explains.

It may seem like a relative straight line for Allen’s career path, but he knows as well as most who have successfully arrived at the top of their game that it requires hard work. “Study hard,” he reminds those at the U who are just beginning their academic and professional careers. “Accept challenges and learn from mistakes (both your own AND the mistakes of others).” Setbacks and failures, he concludes, “are stepping stones toward great success!”

The current pandemic has been one of those setbacks for many, including Allen. “Covid-19 has caused our group and the hospital systems we provide services for to streamline our processes and has really pushed us to embrace the use of technology to enable us to communicate with patients and other medical providers in new ways,” he says. “Although it has significantly limited in person interactions, Tele-Health interactions have increased significantly and have enabled us to provide services that were once difficult or impossible to provide.”

It’s not just about work for Allen. A fluent speaker of Brazilian Portuguese, he says he enjoys the great outdoors with his family and his personal hobbies of camping, fishing, water sports and photography.

For Jason Allen, the University of Utah and the School of Biological Sciences was not only the portal for his early initiation into science and medicine, but it turbo-charged his career through early experiences in research, or as he puts it, “at the bench,” not only in the lab but in life.
