The Sandra J. Bromley scholarship is a full-tuition scholarship for undergraduate students in the College of Science. It provides in-state tuition, up to 15 credit hours per semester, for eight semesters which allows each recipient to complete their degree. The program, now celebrating its 10-year anniversary, is funded by the generosity of Ray Greer, BS’86, in Mathematics.

Each year, a freshman student is selected as a new Bromley scholar, and rolls into the program, while a senior student graduates. This unique model provides continuous funding to the students and allows the College of Science to assist and monitor the students as they progress through their academic program.

“The Bromley scholarship is extremely valuable because it can serve a student throughout their entire undergraduate career,” says Peter Trapa, dean of the College of Science. “The cumulative effect for the student is truly profound. Each year we see the incredible results.”

In addition, Greer and his wife, Jill, host the Bromley scholars at least once a year on campus. The informal luncheon allows the students to report on their progress and discuss any problems or concerns.

“I have had the pleasure of meeting and getting acquainted with the undergraduates as they progress through their academic goals, and it is always a pleasure to see their progression and academic interest flourish over time. In all I have done throughout my life, this has been one of the greatest and most rewarding experiences I have had the opportunity to be a part of,” says Greer.

Role Model

When Greer was just 12 years old, his mother, Sandra J. Bromley, moved her young family from Texas to Utah. The year was 1976. Bromley was promptly hired at the University of Utah and enjoyed a successful career as a technical illustrator in the College of Mines and Earth Sciences under the direction of Frank H. Brown.

“My mother was the single greatest influence in my life,” says Greer. “She taught me the value of hard work and perseverance. She also insisted that college was not optional. It was like going from junior high to high school — you just did it!”

Greer enrolled at the U for fall semester 1981 and was initially interested in computer science and engineering. However, computer science was highly competitive at the time so available classes were scarce.

“Fortunately, Hugo Rossi, a math professor, convinced me that if I majored in mathematics I could get as much course work in computer science as I wanted,” says Greer.

For several years Greer worked through the rigorous mathematics major requirements. He persevered and completed his math degree in 1986.

Then, in 2000, Greer’s mother moved back to Texas for the remaining years of her life. She passed away in 2011. Shortly thereafter, Greer established the Sandra J. Bromley scholarship to honor his mother by providing a way for deserving students to earn a college degree.

“She worked hard to provide for her family, but her greatest regret in life was not attending college herself, hence the vision behind the Bromley scholarship,” says Greer.

“Her requirement was that she would support me as long as I didn’t quit school,” says Greer.  “That is why the Bromley scholarship requires continuous attendance.”

Solving Problems

Greer has more than 40 years of experience in logistics and transportation industries. He has held senior management positions for Greatwide Logistics Services, Newgistics, Ryder Logistics and FedEx. He served as president of BNSF Logistics, headquartered near Dallas, Texas, from 2011 to 2018.

“Math allows me to think critically about situations and problems generally. Not just numerically but logically, to find patterns and trends that point to likely outcomes,” he says.

In 2018, Greer was named CEO of Omnitracs, a leading company in onboard technology for the transportation industry. Omnitracs is an international billion-dollar company that provides telematic devices and logistics to support drivers and their organizations to be compliant, safe and efficient.

“Math is universal and most importantly it teaches you discipline and persistence to work a problem until it is solved. That process of critical thinking and problem-solving has served me well throughout my entire career,” says Greer.

In 2021, Greer sold Omnitracs and transitioned to advisory board work as well as becoming an operating partner for Welsh, Carson, Anderson and Stowe, focused on supply chain technology investments.

Ray Greer has high hopes and expectations for today’s college students. His advice: “Connecting with people — not apps and cell phones — will differentiate you from the competition.”

The Bromley Scholars


Eliza Robert
“I love the entire vibe of the university”


Eliza Roberts is the most recent recipient of the Bromley scholarship. A freshman at the U, she is pursuing a degree in applied math and physics, with an emphasis in astronomy and astrophysics. Being awarded this scholarship has made Roberts’ experience at the U even more valuable. “It has truly allowed me to focus more on my classes, and even take classes that I wouldn’t have taken otherwise,” she says. “With the scholarship, I don’t have to worry about the financial aspects of college like I was fully intending to, which means that I can explore my passions and dedicate my time to learning.”

In addition to her hard work as a student, Roberts works as a math tutor in the TRIO office at the U. One of her proudest accomplishments is receiving her Girl Scout Gold award, for which she focused on creating a safe backyard space for adults with disabilities. 

Roberts lives in Salt Lake City and makes the most of her time at the U participating in LEAP classes, a year-long learning community for entering University students, and even discovering top-secret study and nap spots on campus. “I love the entire vibe of the university,” she says. “I feel safe, valued, and free. I have been able to explore myself more than I have in years, and it has helped me figure out who I want to be.”

Dannon Allred
“Space is simply beautiful”


Dannon Allred was awarded the Bromley Scholarship in 2021 and just completed his sophomore year at the U. A passionate learner, he is studying physics with an astronomy emphasis. “Ever since I’ve been interested in science, I’ve felt a pull towards physics and astronomy,” he says. “There’s just a lot in astronomy that spikes my curiosity, there’s a lot that’s unknown, and [outer] space is simply beautiful.”

The Bromley scholarship has given Allred the opportunity to experience college without any financial worries and has allowed him to focus more of his energy on his passion for astrophysics. “Obviously one of the most daunting things about college is paying for it, and that’s a lot of stress that most students have to deal with,” he says. “I would say that’s what’s most impactful about the Bromely scholarship because it allows me to go through college stress-free in that aspect.” 

On top of his astrophysics studies, Allred has been involved in several research projects on campus. “In my freshman year, I was part of Dr. Boehme’s … lab as part of the Science Research Initiative doing research on Organic Light-Emitting Diodes (OLEDs) using spintronics,” explains Allred. “This spring, I did an introductory research project analyzing the spectral emission features of the Sombrero Galaxy with Dr. Anil Seth” who specializes in astrophysics. 

Allred’s hope is to complete a graduate degree in the field as well. Not surprisingly, when he’s not busy studying stars and galaxies far, far away, he loves astrophotography, admiring the universe through the lens of his camera.   ~ Julia St. Andre

Michaela Fluck
“Proceeding Into the Wilderness”

Michaela Fluck works in the Zelikowsky Lab, which researches neural circuits that affect stress, fear, and social behavior. “I’ve always been interested in neurobiology, since I was a kid,” she states. “I’ve had family members who’ve had strokes and other brain injuries.”

A biology major with a psychology minor, Fluck says the study of abnormal psychology is also a passion of hers. “Seeing what can go wrong with the brain and what’s behind [it] …  is super interesting as well.”

Fluck was inspired to become a doctor by her patients at Primary Children’s Hospital, where she works as a phlebotomist. “I want to become an advocate for patients,” she says, “and help people work through the difficulties of medicine. Kids tend to hate procedures no matter what, so helping them work through the procedures is honestly one of the most rewarding things I’ve ever done.”

Her favorite class was organic chemistry. “Not a lot of pre-meds can say that,” she jokes. Fluck also loved taking an acting class at the U which relieved the stress of being a STEM student and harked back to her time as an actress in high school, especially her appearance in the the late Stephen Sondheim’s epic musical saga about daring to venture Into the Woods.  ~ CJ Siebeneck

Keegan Benfield
“Who knew I could do that?”

As a Bromley Scholar, Keegan Benfield BS’23, was able to spend more time on scientific passions, such as research and projects. “The Bromley Scholarship and the U have helped shape me to be the best that I can be.” 

Along with his double majors in mechanical engineering and physics, Benfield focuses his time on humanitarian efforts, volunteering with Youthlinc and Real life programs. He’s the president of the university’s marksmen club, and has attended National Collegiate events at the National and Junior level.

Prior to graduation, Benfield worked in the Deemyad Lab, researching condensed matter physics. The Lab focuses on theoretical physics, especially the physics of matter at extreme conditions of temperature and pressure.

One of Benfield’s favorite classes was Introduction to Relativity and Quantum Mechanics. “It was an ‘ah-ha!’ class that was challenging and fun,” Benfield says. “I have learned and expanded my knowledge in ways that amaze me. Who knew I could do that?”

Benfield recently completed a summer internship at Cosm and developed educational programs for planetariums using Digistar 7, which features full-dome programs and production services, giant screen films formatted for full-dome theaters, premium-quality projection domes, and theater design services. He plans on getting a master’s or PhD and work in a national laboratory or research company.   ~ CJ Seibeneck

Nobel winner Capecchi discovers new brain mechanism

June 13, 2023

The pandemic and its aftermath have raised anxiety to new levels. But the roots of anxiety-related conditions, including obsessive-compulsive spectrum disorder (OCSD), are still unclear.

In a new study, University of Utah Health scientists discovered insights into the importance of a minor cell type in the bra in — microglia —i n controlling anxiety-related behaviors in laboratory mice. Traditionally, neurons — the predominant brain cell type — are thought to control behavior.

The researchers showed that, like buttons on a game controller, specific microglia populations activate anxiety and OCSD behaviors while others dampen them. Further, microglia communicate with neurons to invoke the behaviors. The findings, published in Molecular Psychiatry, could eventually lead to new approaches for targeted therapies.

“A small amount of anxiety is good,” said Nobel Laureate Mario Capecchi, Ph.D., a distinguished professor of human genetics at the Spencer Fox Eccles School of Medicine at University of Utah and of biology in the School of Biological Sciences. He is also senior author of the study. “Anxiety motivates us, spurs us on, and gives us that extra bit of push that said, ‘I can.’ But a large dose of anxiety overwhelms us. We become mentally paralyzed, the heart beats faster, we sweat, and confusion settles in our minds.”

“This work is unique and has challenged the current dogma about the role of microglia function in the brain”

Capecchi, who arrived at the University of Utah in 1973 did much of his early research, leading to his Nobel Prize, at U Biology where a permanent display of his original equipment involving gene-targeting is housed.

Geologist Brenda Bowen, to chair Department of Atmospheric Sciences

June 12, 2023

The College of Science and the College of Mines and Earth Sciences (CMES) are pleased to announce that Professor Brenda Bowen has agreed to serve as the next chair of the Department of Atmospheric Sciences (ATMOS).

Bowen is a Professor of Geology and Geophysics and Director of the Global Change and Sustainability Center (GCSC). She will continue as the Director of the GCSC while serving as chair and will replace John Horel who has been at the helm of ATMOS for five years.

“Brenda Bowen is an internationally prominent researcher and an experienced academic leader,” said Peter Trapa, Dean of the College of Science. “Bowen’s vision will guide the Department of Atmospheric Sciences in exciting new directions.” 

“As most of you know, Brenda is a dynamic leader on campus who has a collaborative vision of academics and research,” said Darryl Butt, out-going dean of the CMES to his colleagues. “I am really looking forward to watching the synergy between departments in our merged college structure as you all continue to break down barriers of academics and, as I like to say, make two plus two equal something greater than four.”

 Said Bowen who begins her tour as chair on July 1, 2023, “I am excited for the opportunity to serve as Chair of Atmospheric Sciences.  I look forward to leading ATMOS in a way that creates stronger connections between our departments and the College of Science as a whole. My goal is to build on the department’s leadership in advancing field stations and long-term field-based science, commitment to conducting and advancing community-based research with highly significant societal relevance, and dedication to training students for careers of the future.”  

An interdisciplinary geoscientist, Bowen explores the links between sedimentology, geochemistry and environmental change, particularly in extreme environments.  Recent work is focused on how surface process, groundwater flow and geochemical change impact landscape evolution in human-modified systems using field observations, satellite and airborne remote sensing and a range of lab-based analytical techniques including geochemistry and microscopy. 

In addition to her geologic research and teaching, Bowen works to facilitate interdisciplinary sustainability research, practice, and academic programs that address critical issues related to understanding global change and creating sustainable solutions related to energy, resources and climate.

ATMOS is the leading program of weather and climate related research and education in the Intermountain West and is recognized internationally for its expertise in cloud-climate interactions, mountain meteorology, climate physics and dynamics, weather and climate modeling, and tropical meteorology. The department, which celebrated its 75th anniversary earlier this year, houses research and teaching endeavors that provide the knowledge and tools needed by society to address the challenges posed by hazardous weather and climate change in the 21st century. The department is a student-centered department with faculty who are dedicated graduate student mentors and classroom instructors. Several of ATMOS professors have won college or university-wide teaching awards. For more information, read the department’s 2023 magazine Air Currents.

 

Tinker Toy Rises

June 9, 2023

After months of earth-moving, the Applied Science Project gets some serious hardware.

These days pedestrians along University Street on the westside of campus are typically met by Alan, a bearded, sixty-something employee and certified UDOT flagger dressed in Okland Construction garb, including hard hat with neck sunshade that cascades to his shoulders and sometimes flaps in the wind. Alan’s here keeping order at the gated threshold to the construction site of the Applied Science Project and is happy to give you a fist bump as you walk to work along the detour they’ve put up. Armed with a push broom, and a mobile phone, he slows traffic for entering and exiting trucks, and lines up arrivals carrying everything from timbers to a porta-potty called “Honey Bucket.”

On the morning of June 7th, the team was preparing for the delivery of a giant tower crane, in sections, which will stand around 265 feet tall for a full year at the site like a giant Tinker Toy. A tower crane features a jib or “jib arm” as a horizontal beam used to support the load clear of the main support. It can typically lift 19.8 tons (18 metric tons).

“So these cranes are so big they need to have all these counterweights and stuff,” says Carlyn Chester BS’09, Senior Risk and Safety Manager at Okland Construction. She spells her name for us: “Like George Carlin [the late sometimes raunchy comedian] but with a ‘y’ . . . and I’m not a dirty old man,” she says with a laugh. Chester oversees all of the many Okland projects at the University of Utah.  The cranes need to be “strong enough to pick up those tower pieces,” she continues over the relentless beeping of a nearby steer loader pushing gravel.  “You need a crane to build a crane. You have to put in all the counterweights and footings . . . [There are] two big semis worth of materials just to get that crane set up tomorrow before the tower crane comes in.”

The gaping hole in front of the old Stewart Building—site of the new Applied Science Building—is squared off with wooden bulwarks holding up the sides (temporary) backed by a cement retaining wall (permanent). It looks like a neatly squared-off grave for a giant of sorts, two stories deep at the back and the sides sloping down the hill to a mere curb at the street. It’s a striking contrast to the bucolic Cottam’s Gulch with its brick path and towering hybrid trees to the north which will be a preserved historic asset to what will become the College of Science’s Crocker Science Complex.

“Did you find any bones?” we ask. Back in 2017 when the George Thomas Building was being retrofitted and expanded for the Crocker Science Center, Okland unearthed human bones that turned out to be the remains of old cadavers that had been discarded decades earlier by the medical school, originally located in the Life Sciences Building, another Okland project on campus.

“We found a couple of things,” says Chester. “The paleontologist people were here every single day when we were digging.” (It turns out the bones were from modern animals.)

Carlyn points at a boxy, hexagonal structure to the left where a temporary footing has been positioned in the bottom of it. The footing is inspected by a structural engineer “to make sure it’s level and plumb so that when we start building, [the tower crane is] stable. There’s so much science that goes into it and mathematics,” she says.

Meanwhile, Alan has ambled back to the street to talk to a truck driver who has just pulled up. When he returns, he and Carlyn pose for a picture together­–all smiles under their hard hats and neck shades that faintly remind one of Lawrence of Arabia’s. Alone, we ask Alan to “Flash the U” for us which he struggles a bit with. “My dad went to BYU,” he says sheepishly.

Bright and early next morning, Alan was back giving his signature fist bumps to passers-by. They stopped for a few moments to witness the newly arrived crane-to-build-a-crane with a synchronized telescoping boom as high (or higher) than one of those vertiginous, gut-wrenching rides at Lagoon amusement park north of here. Soon the semis arrived with tower segments which were off-loaded, rigged and then lofted off the ground vertically.

Even the rowdy fox squirrels in Cottam’s Gulch paused in a moment of awe as the Tinker Toy began to rise, a flash of yellow latticed steel against the summer sky.

Randy Irmis receives Fulbright Scholar Award

June 6, 2023

“How we look at fossils,” says paleontologist Randy Irmis in a 2016 interview, is the most exciting thing happening in his field today. “There are a lot of new ways to look at fossils rather than just observing the bones themselves. We have lots of new imaging techniques for looking inside bones or skulls and doing three dimensional work.”

The Chief Curator and Curator of Paleontology at the Natural History Museum of Utah, and Associate Professor in the Department of Geology & Geophysics, Irmis recently received a Fulbright U.S. Scholar award.  He was one of two University of Utah professors to receive the honor, the second being Michael Yu, a member of the Department of Biomedical Engineering.

Irmis, who as a Fulbright will be associated with the Instituto Argentino de Nivologia Glaciolgia y Ciencias Ambientales in Mendoza, Argentina, has a whole lot more to say about dinosaurs, including molecular work in the field “looking at the composition of the bones and sometimes feathers or hair that was preserved. We’re learning a whole bunch of new things just by the way that we can image these fossils using very advanced techniques that we never would have dreamed of even ten years ago.”

In Argentina, Irmis will develop and teach a new field-based course on methods and approaches to interrogating the geologic record on how terrestrial ecosystems changed in relation to climate in deep time and collaborate with Argentine colleagues on a large-scale research project to understand how Triassic non-marine ecosystems in northwestern Argentina changed in relation to the regional and global environment between 250-215 million years ago.

U.S. Assistant Secretary visits U and Utah FORGE site

June 6, 2023

Managed by the University of Utah, the Utah Frontier Observatory for Research in Geothermal Energy (FORGE) hosted Alejandro Moreno, acting assistant secretary for the U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy, for a two-day visit to the University of Utah and the Utah FORGE site, during which he learned about geothermal energy and the ongoing research in Beaver County.

Utah FORGE is a geothermal laboratory located northeast of Milford. The $218M project was awarded to the U’s Energy & Geosciences Institute after a three-year, five-way competition, and is the university’s largest-ever research grant. Along with the FORGE team, Assistant Secretary Moreno was joined by Lauren Boyd, acting director of the DOE’s Geothermal Technology Office, and several other officials from the department.

The visit comes about a month after FORGE announced that the drilling of its second highly deviated deep well has commenced. This second well will serve as the production well of a two well doublet, and will mirror the existing injection well, which was drilled between October 2020 and February 2021. The new well will be located approximately 300 feet from the injection well.

Like the injection well, the upper part of the well will be drilled vertically through approximately 4,550 feet of sediments at which point it will penetrate into hard crystalline granite. At about 5,600 feet, the well will be gradually steered at a 5-degree angle for each 100 feet until it reaches an inclination of 65 degrees from its vertical point. The total length of the well will be approximately 10,700 feet with the “toe” – or the end of the well – reaching a vertical depth of 8,265 feet. The temperature at this depth will be 440 degrees F.

Dr. Joseph Moore, the principal investigator of Utah FORGE, Research Professor in the Department of Civil and Environmental Engineering and adjunct faculty member in the U’s Department of Geology & Geophysics in , presented an overview of the project and answered questions from the Assistant secretary and others in attendance. Assistant Secretary Moreno was eager to learn more about the potential offered by the research in Enhanced Geothermal Systems (EGS), the progress achieved thus far, and its role in advancing the nation’s renewable energy goals.

2023 Outstanding Undergraduate Research Mentors

June 2, 2023

The Office of Undergraduate Research has created a faculty award to honor mentors for their work with students. The Outstanding Undergraduate Research Mentor Award, now in its inaugural year, is given to those who were selected by their college leadership and peers for their dedicated service to mentorship.

Of the 420 mentors across campus who worked with the Office of Undergraduate Research this year, two of the 2023 winners of the Outstanding Undergraduate Research Mentor Award are seated in the College of Science: Ofer Rog (biology) and Gannet Hallar (Atmospheric Sciences).

Dr. Ofer Rog’s research focuses on the complex regulation of chromosomes during meiosis. Dr. Rog and his assembled team of top-notch researchers have developed new methods, used innovative approaches, and carried out meticulous studies that are now revealing key elements of this complex process. The work conducted by him and his research group has provided stunning insights into the fundamental cellular processes explaining the origin and maintenance of different sexes, including our own. As Director Frederick Adler states, “Dr. Rog is also an extraordinary communicator with a dedication to helping colleagues and students find new ways to communicate.”

The Mario Capecchi Endowed Chair in the School of Biological Sciences (SBS), Rog was a catalyst in forming and managing the LGBTQ+ STEM interest group in the College of Science. The group seeks to create change in our campus community with an inclusive environment for LGBTQ+ individuals and allies.

You can read about Rog’s work with condensate illustration in a recent feature in SBS’s OUR DNA here.

 

Dr. Gannett Hallar has been successfully mentoring undergraduate researchers at the University of Utah since 2016. Her mentees participate in the Hallar Aerosol Research Team (HART) making connections between the atmosphere, biosphere, and climate. Her mentees have successfully received awards such as the Undergraduate Research Opportunity Program and Wilkes Scholars. Her commitment to mentoring includes her role as a faculty fellow with Utah Pathways to STEM Initiative (UPSTEM), training in inclusive teaching and mentoring strategies.

As stated by Dean Darryl Butt, “Dr. Hallar is a world-class mentor. Her dedication to our undergraduate students comes naturally, but she is also very deliberate in creating a structure of experiential learning that is inherently unforgettable.”

Director of the Storm Peak Lab, the premier, high-elevation atmospheric science laboratory in the Western U.S., Hallar says the facility atop Steamboat Springs Ski Resort is “the perfect place, to have your head in the clouds.” The laboratory sits in the clouds about 40 percent of the time in the winter. “That allows us to sample clouds and the particles that make clouds at the same time. And from that, the lab has produced about 150 peer-reviewed publications.”

An Unexpected Climate Solution

June 2, 2023

The Wilkes Center Student Innovation Prize

Nicholas Witham is the first-place winner of the Wilkes Center Student Innovation Prize, awarded earlier this month at the University of Utah. The competition invited students to propose creative solutions for tackling the climate crisis, along with presentations that detail their potential impact, benefits, and practicality. Three other prizes, one for second place and two for third place, were also given during the inaugural Wilkes Climate Summit at the University of Utah, May 17-18.

A graduate student at the U, Witham is currently pursuing his Ph.D. in biomedical engineering, as well as running his company Gaia Technologies which makes prosthetic components. For the Wilkes Center Prize, he designed an innovative renewable electric generator that relies on natural fluctuations in the Earth’s temperature. “The type of generator I’ve designed works with thermo-motive artificial muscles,” he says. “That means that they contract when you heat them. Every day the Earth gets hotter and colder which will make them move, and they can pull on a turbine, generating power. The great thing about this is that cooling also generates power, so you can make energy day and night.” This potential for around-the-clock power generation could help to bridge the energy gap that is common with renewable energy sources. 

One of the first places Witham hopes to put his generators is in Southern Utah where the day-to-night temperature change is ideal for this technology 10 months out of the year. And although natural temperature fluctuations may not always be enough to run the generators, Witham believes that they could be used to complement existing renewables such as solar and geothermal energy: “You can use highly efficient geothermal heat pumps to actuate them without needing to have a temperature change caused by the environment. The excess heat that they are wasting, not spinning a turbine, just cooling down before they pump it back into the Earth–we could use that to increase the energy output of our generators tenfold,” he says. 

In fact, installing these generators at pre-existing geothermal plants or solar farms may be the most ideal option to maximize the efficiency and cost of these sites. “I ran the numbers, and I believe that this could be a solution that could cost less than solar, and you can scale it vertically,” explains Witham. “So you could use existing solar infrastructure, place the solar panels on top, and any time you want to reinvest in the site without having to run new electric lines to it, you could just stack them higher.” 

Not only is the generator a potentially powerful form of renewable energy, but it also incorporates carbon capture into its design. “These are polymer textiles. So they’re made out of a plastic called linear low-density polyethylene (LLDPE), which is a type of plastic that can be bio-derived. That means you can use corn husks to make this plastic as an indirect form of carbon capture. Every kilogram of LLDPE sequesters 3 kilograms of carbon.” 

Witham carefully considered the environmental impact of these generators, ensuring that they contribute to carbon sequestering efforts instead of creating more waste: “In the decommissioning of solar panels, for example, you generate quite a lot of e-waste. This system is designed to be recycled and decommissioned in an environmentally safe practice.” 

Witham plans to house the entire generator inside a shipping container, and he estimates that one of these generators could be expected to last over 25 years with very minimal maintenance. Due to their self-contained nature, the impact and effect of these units on the surrounding environment is very minimal. “It’s essentially a big black box that we plan to put in the middle of the desert. I contacted the local EPA office about this to see if there was anything I was missing, and they had no real concerns. Because we’re putting it in a box, any microplastics that might be generated by the textiles shearing or breaking catastrophically would be contained,” he states.

The capacity for incorporating these devices in urban areas, according to Witham, may be limited to apartment buildings or skyscrapers. “I don’t think anybody really wants to use a shipping-container-sized portion of their yard to make power,” he jokes. The weight of these containers also limits their ability to be placed on top of roofs, or buildings, as each unit weighs roughly 18 metric tons. However, there is potential for them to be incorporated underneath buildings. “You can absolutely put it underground if you have a heat pump HVAC system to regulate it, but that would be a bit less efficient.” Though the generators wouldn’t function as well as in the remote desert environment Witham has planned, there is still a possibility for urban incorporation. 

With a purse of $20,000 from the Wilkes Center Prize, Witham is one step closer to getting his design up and running at full scale. His lab already has the capability to mass-produce the necessary artificial muscle technology, so a prototype will soon follow. “The assumption is that we can make a nine-megawatt-hour generator at scale to test it in the field. From there we could make a generator field just like you would see for a solar field. And then with a 2.4-year doubling period – which is typical for renewables in this area – that would mean that by 2050 we would have sequestered and offset a total of 15 million tons of CO2.” Witham’s consideration of sustainability, feasible scaling, and collaboration with other renewables make his design both practical and effective as a climate solution.

Clearly, the judges of the Wilkes Center Prize thought so as well. Witham’s design is a unique and impressive fusion of renewable energy with pre-existing biomedical technologies, showcasing that the nature of climate solutions will likely be interdisciplinary. Witham jokes that a sleepless night at work is to thank for his idea to incorporate his biomedical work into a renewable energy source: “I was having a sleep-deprived night in the lab, as you do as a graduate student,” says Nicholas Witham, “and I crunched the numbers because I thought, ‘hey, the Earth heats up!’ I connected all the dots because we use a type of plastic that is a lot more energy efficient and is not typically used for these artificial muscles. And that energy efficiency really allowed this idea to have merit.” 

Witham’s creative application of biomedical engineering shows that the most powerful climate solutions may come from unexpected places and that no branch of knowledge is too isolated to make an impact. His impressive design stands alongside dozens of other projects from creative and dedicated students that rose to meet this innovation challenge. With prizes such as this, the Wilkes Center for Climate Science and Policy is leading the way toward creating a powerful forum for interdisciplinary climate solutions and collaboration, essential for tackling a multifaceted issue like climate change.

Vulnerable forests and the carbon budget

 

Jon Wang is an Earth systems scientist and recently joined the faculty of the School of Biological Sciences as an assistant professor. 

Born and raised in California, Wang’s undergraduate degree took him across the country to Brown University where he studied biology and geology. “It was the major that had the most field trips,” jokes Wang. “And if I could go outside as part of school, that sounded great. It really set me down on this path of trying to understand the Earth system overall, and how biogeochemical cycles like the carbon cycle or nutrient cycles interact and form the world as we know it today.” 

Wang’s current research revolves around understanding environmental changes to ecosystems in places like Canada and Alaska, where rapidly warming temperatures are re-shaping the variety of plant life that grows in those areas. “In the far north, it's warming faster than anywhere else on the planet. And that's causing what we call a biome shift,” explains Wang. By utilizing decades of satellite data from sources such as NASA, Wang is able to observe changes to these ecosystems over long periods of time by combining machine learning and data science to transform the satellite information into useful datasets. Having a big-picture view of these ecosystems helps inform these scientists about where, when, and why certain ecosystems have changed, and what that means for addressing climate change.

Wang recalls the course that compelled him to dive into the trove of forest and ecosystem data:  “There was one course I took at the end of my time at Brown called Environmental Remote Sensing which was focused on trying to understand how we use satellites to measure changes on the Earth's surface. I decided that that was one of the best combinations of geology, biology, physics, and engineering. So I decided to go back to grad school and pursue a Ph.D. and try to advance this kind of research.” 

With climate change at the forefront of global conversation as he began his Ph.D. at Boston University, Wang says he felt compelled to be more involved with research surrounding climate solutions. “Things were starting to feel pretty serious, and I felt like I was really outside of all of it, you know, working and trying to pay off student loans. I decided that I wanted to try to understand that whole issue a lot better. So that's how I got connected into trying to understand forests and the role they play in the Earth system, and how they may potentially serve as a solution for the climate crisis.”

Wang began his career by researching urban heat islands and forestry in an effort to understand the role that trees play in urban ecology, carbon capture, and human health. Though there are fewer trees in cities, they play an important role in the absorption of carbon emissions. “We were working towards a better understanding of urban ecology so we can account for the urban forest part in this carbon budget, and that can in turn improve our ability to evaluate these carbon emissions programs that cities are trying to implement,” says Wang. Closer to home, Wang also studied the California wildfires and their impact on both urban and wild areas.  

As he begins this new chapter as a professor, Wang is excited to teach a new generation of scientists as they explore everything Earth science has to offer. During his undergrad, Wang was a participant in the NASA Airborne Science Program (SARP) which maintains a fleet of aircraft used for studying Earth system processes, calibration/validation of space-borne observations, and prototyping instruments for possible satellite missions. After returning to the SARP program as a mentor, Wang was compelled to start teaching. “I loved that experience where I just got to meet a lot of different young minds. They don't know what they want yet, but it's really cool to see that they have this whole world of Earth Science open to them. It was really inspiring.”

Related to his experience with airborne data collection, Wang is planning on using unmanned aerial systems (UAS), to generate very high resolution maps of forest structure and stress for calibrating space-borne satellite data. UAS's, commonly known as "drones," can help measure the temperatures of leaves to understand climate-induced stress and mortality or measure greenness to track the changing of the seasons at a tree-by-tree level. "It's fun," he says, "because it's like playing video games, but outside and for science!"

As his work deals heavily with climate change, Wang is careful to remain optimistic when it comes to the future. “I think there is a big shift in the broader culture about how these systems work, and there's a better understanding of how everything's connected. We're worried that this biospheric carbon sink is vulnerable to climate change, but it's there, and there's a capacity for the Earth to take the carbon back, to mitigate this climate change, and to give us some ability to reverse the damage. And in the meantime, there's all this research and motivation to learn how to adapt to what's going on. So I think there's a lot of hope. There's a lot of reasons to be skeptical and a lot of reasons to be concerned for sure, but despair is definitely not going to get us anywhere.”

As he begins his time in the School of Biological Sciences at the U, Wang is thrilled to be joining a community of scientists with complementary areas of research and looks forward to working closely with them to expand our understanding of our changing world. “There’s a really neat hub of carbon cycle and Earth science research that I knew I wanted to be part of. And so I feel really lucky that I have the opportunity to join this department and really plug into that whole world of research.”

Wang draws inspiration from many sources, including Utah’s beautiful mountain scenery, as well as the work of Katharine Hayhoe at the Nature Conservancy and Texas Tech and Michael Mann, a professor, and author from the University of Pennsylvania. Wang admires their pioneering public discussions of climate change and commitment to awakening the public to a more nuanced view of the issue.

When Jon Wang's not busy looking out for the future of our planet, he enjoys Taiko, a type of athletic ensemble made up of drums called wadaiko. Known as “The Japanese Art of Drumming,” the exciting and vibrant Taiko is witnessed globally, but it is most often performed in Japan, where it originated. He also enjoys mountain biking and caring for his new puppy "Muesli."

The Association of Universities for Astronomy (AURA) is pleased to welcome two new member institutions: the University of Utah and the University of California at Los Angeles (UCLA). Both institutions’ applications to join AURA were approved by AURA’s Member Representatives at its April annual meeting in Tucson, Arizona.

University of Utah astronomy

Established in 1850, the University of Utah is the flagship university of the state. A community of students, staff and scholars, the University of Utah—affectionately called “the U”—is dedicated to the advancement of knowledge through innovative research; the education of future citizens, professionals and leaders; and scholarly and creative pursuits that preserve and broaden our understanding of the human condition. The U prepares students for leadership roles in Utah, the country and the world. Located in one of the darkest states in the nation, housing the Consortium for Dark Sky Studies and launching the first-ever minor in dark sky studies in the U.S., the U is a leader in exploring the impacts of artificial light at night and the loss of our night skies through a broad range of disciplines.

The University of Utah’s Department of Physics & Astronomy in the College of Science is committed to pursuing key science questions within an inclusive academic community; to training and diversifying the next generation of researchers, educators and technology workforce leaders; and to inspiring an appreciation for knowledge in students and the wider community.
