2022 Outstanding Graduate Student

Daniel Powell named 2022 College of Science Outstanding Graduate Student.

Having completed his B.S in Chemistry here at the U, I was extremely thrilled when Danny joined my research group in the spring of 2016. This was surprising since I was listed as a Materials Chemistry Professor as opposed to an Organic Chemistry Professor (organic synthesis is Danny’s forte). As a young Assistant Professor, I was in desperate need of a student with strong organic synthesis skills that could push the development of solution-processable and high efficient organic electronics to another level and Danny certainly delivered!. With my laboratories in their infancy, Danny displayed both the initiative and drive to push through all the troubleshooting that is required to take a novel idea and turn it into a full-fledged research project without the luxury of senior students to mentor him.

Danny displayed both the initiative and drive to push through the troubleshooting that is required to take a novel idea and turn it into a full-fledged research project.

 

As Danny’s Ph.D. mentor, I have had the opportunity to experience first-hand how he has grown scientifically throughout the challenges of his research projects and his ability to independently solve scientific problems, while staying enthusiastic and engaged. He has repeatedly demonstrated himself to be eager to face and conquer scientific challenges with high ambition and strong work ethics. Danny’s dissertation work displays effectiveness in managing multiple projects with different reaction mechanisms and materials undergoing optical and structural heterogeneities that are often difficult to elucidate. Driving these complex projects to completion illustrates his organizational skills, self-motivation, and independent nature.

Danny was actively engaged with the Lassonde School of Entrepreneurship during his graduate studies. It is quite rare that graduate students will pursue extracurricular activities during their graduate studies given the difficulty and attention it requires, yet Danny not only participated but excelled in this area as well. I have to say that Danny is a very talented scientific communicator and writer!. Often, his papers were ready to be submitted without much addition from my end. He also helped me write ≈85% of a recently funded NSF proposal. I have to admit that I would dearly miss him when he is gone.

Danny recently defended his PhD work and will be joining Blackrock Neurotech (a company housed in Research Park dealing with the development of implantable neurological devices). At Blackrock Neurotech, he will be responsible for seeking both federal and investor funding for the company. I am very sure he will be very successful in his future endeavors.

May 8, 2022

2022 Research Scholar

Tyler Ball named 2022 Research Scholar by the University of Utah - College of Science.

Tyler Ball is a first-generation college student who grew up in Salt Lake City. She enrolled at the University of Utah in 2018 and participated in the ACCESS Scholars program as a member of the 2018-2019 cohort. Through the ACCESS program, Tyler was introduced to broad topics related to sustainability which cemented her desire to pursue a degree in chemistry. The program also enabled her to get involved with research during the second semester of her freshman year – she joined Dr. Matt Sigman’s lab in January 2019.

Her first research project was a mechanistic study of the oxidative addition of cobalt complexes into benzyl bromides using electroanalytical techniques, which was published in the Journal of the American Chemical Society in October 2019. She was hoping to expand on this project using different substrates, but the COVID-19 pandemic pushed her to start a fully computational project in the spring of 2020. Tyler began a project using Symmetry-Adapted Perturbation Theory to study trends within and between different types of non-covalent interactions. She is currently working toward publishing this effort in the near term. In an effort to expand the breadth of her research experience, Tyler participated in an NSF-funded REU program at the University of Minnesota during the summer of 2021. Working with Professor Ian Tonks, she evaluated cobalt catalysts for the hydroesterification of small molecules.

Tyler’s learning is propelled by her passion for sustainability. During her sophomore year, Tyler became involved with our American Chemical Society Student Chapter’s Green Chemistry Committee (GCC).

 

During the fall of 2020, Tyler applied for the Goldwater Scholarship and earned the award in March 2021. Alongside the prestigious Goldwater Scholarship, Tyler has earned various awards through the Department of Chemistry and the College of Science, including the College of Science Dean’s Scholarship and the Leon Watters Memorial Award.

Tyler’s learning is propelled by her passion for sustainability. During her sophomore year, Tyler became involved with our American Chemical Society Student Chapter’s Green Chemistry Committee (GCC). The GCC helped to introduce Kimberly Clark’s glove recycling program into teaching and research labs in the chemistry department and recently worked with the College of Science to introduce mask recycling into lab spaces. Tyler’s involvement in the GCC has also helped her to focus on outreach efforts – she has organized multiple outreach events this year, with the hope of earning a Green Chemistry Award for the student chapter through the national ACS organization.

Going forward, Tyler will be pursuing her PhD in chemistry at Cornell University. Her emphasis will likely be in green catalysis with an application to polymer synthesis and her studies will be funded by the NSF Graduate Research Fellowship Program. She is incredibly grateful for all the opportunities the College of Science has afforded her during her undergraduate studies and the supportive community of scientists she has been able to surround herself with.

Outside of the lab, Tyler enjoys hiking and rock climbing. She is always looking for vegan recipes to cook and loves trying new restaurants around SLC.

 

 

National Academy of Sciences

May 4, 2022

National Academy of Sciences

Valeria Molinero elected as a member of the National Academy of Sciences.

Molinero is the Jack and Peg Simons Endowed Professor of Theoretical Chemistry and the director of the Henry Eyring Center for Theoretical Chemistry. She is a theoretical chemist and uses computer and statistical models to explore the science of how crystals form and how matter changes from one phase to another down to the atomic scale.

Much of her work has involved the transition between water and ice and how that transition occurs in the formation of clouds, in insects with antifreeze proteins, and in food products, especially those containing sugars. Her work has implications for any process in which control of the formation and growth of ice crystals is critical, including snowmaking at ski resorts, protection of crops from freezing, preservation of human organs and tissue for transplant, and production of ice cream and gelato, her favorite food. In 2020, she and her international colleagues demonstrated that the smallest possible nanodroplet of water that can freeze into ice is around 90 molecules, a finding that earned them the 2020 Cozzarelli Prize from the journal Proceedings of the National Academy of Sciences.

She is a fellow of the American Academy of Arts & Sciences and recipient of several U awards, including the Distinguished Scholarly and Creative Research Award in 2019, the Extraordinary Faculty Achievement Award in 2016, the Camille Dreyfus Teacher-Scholar Award in 2012 and the College of Science Myriad Faculty Award for Research Excellence in 2011. She has also been honored by the Beckman Foundation with its Young Investigator Award, and by the International Association for the Properties of Water and Steam with its Helmholtz Award.

Valeria Molina

"There’s satisfaction that comes from seeing someone grow from the beginning of the Ph.D. into an accomplished researcher."

 

Valeria heard about her election between the news of a new publication with postdoctoral scholar Debdas Dhabal and preparations for a doctoral student’s dissertation defense. She received a phone call from colleague Dale Poulter, a distinguished professor emeritus and National Academy of Sciences member, to announce her election. “I was shocked,” she says. “To say it was a surprise would not do it justice. It was fantastic.”

Minutes later, she went into the dissertation defense, reflecting on the range of accomplishments represented by the publication, the election and the defense. “All the research is made essentially there, in the work of the students and postdocs,” she says. “There’s satisfaction that comes from seeing someone grow from the beginning of the Ph.D. into an accomplished researcher.”

Molinero is among 120 U.S. scientist-scholars and 30 foreign associates elected at the Academy’s Annual Meeting in Washington, D.C. She joins 16 other current University of Utah researchers who’ve been elected to the Academy. The National Academies, which also include the National Academy of Engineering and National Academy of Medicine, recognizes scholars and researchers for significant achievements in their fields and advise the federal government and other organizations about science, engineering and health policy. With today’s elections, the number of National Academy of Sciences members stands at 2,512, with 517 foreign associates.

Outstanding Post-Doc

May 2, 2022

Outstanding Post-Doc

Amir Hosseini has received an Outstanding Post-Doctoral Fellow Award from the College of Science.

Amir received his PhD in Chemistry from Indiana University, where he trained with one of the world’s premier organic electrochemists (Dr. Dennis Peters). He then joined the University of Utah in December 2020, as a Postdoctoral Research Fellow in the NSF Center of Organic Synthetic Electrochemistry (CSOE) where he is working in Prof. Henry White’s laboratory.

Amir’s research project is focused on the discovering novel electroorganic transformations and using variety of electroanalytical tools to explore the mechanism of the reaction at the molecular level. Recently, he developed a new synthetic strategy for electrooxidation of alcohols that is refer to as electroreductive oxidation. The general idea is to electrochemically generate highly oxidizing radicals by reduction of a sacrificial reagent, i.e., reduction is used to initiate a desired oxidation reaction. Amir has demonstrated that this process is effective for selective oxidation of alcohols to aldehydes and acids.

Amir Hosseini

Amir is greatly passionate about mentoring and education of the next generation of scientists. He participated in the Science Research Initiative (SRI) program during the 2021 spring semester when he mentored undergraduate students.

 

This mentorship activity included defining research projects, teaching each student the basic knowledge relevant to their research project, and supervising the progress of research projects. Additionally, he has been part of ACCESS program working with other CSOE volunteers to assist students in performing at-home chemistry experiments. Finally, he mentors graduate students, teaching them the fundamentals of electrochemistry and laboratory safety, and advising them on their graduate research.

Equity and inclusion in academic setting is a very important matter for Amir. He is currently serving as the post-doc representative on the DEI committee of the Department of Chemistry. However, his outreach activities are not limited to academia. He volunteers to help new Iranian and Afghan families settling in Salt Lake City. In this role, he assists families who need a translator for taking care of paperwork, enrolling their children in school, and communicating with federal and state officials regarding their urgent needs.

Goldwater Scholar

Goldwater Scholar

Rock climbing in Southern Utah.

Alison Wang, a junior in chemistry, has been awarded a prestigious Goldwater Scholarship for 2022-23.

Alison enrolled at the U in 2019 and declared chemistry as her major, with her eyes set on going to medical school. However, her honors general chemistry professor, Luisa Whittaker-Brooks, encouraged her to seek a research opportunity in Caroline Saouma’s lab as a first-year-student.

Unfortunately the pandemic delayed Alison's start to lab work until fall of her sophomore year, but she came to love research – so much so that she now is planning to enroll in either an M.D./Ph.D. or Ph.D. program.

Her research is focused on mechanistic studies for the electrocatalytic reduction to CO2 to CO or formate at Mn centers. She was a UROP scholar (twice), and participated in the department of chemistry’s NSF-funded REU program last summer.

Alison Wang

These opportunities helped Alison gain valuable skills in communicating science, which she refined in February at the Utah Conference on Undergraduate Research (UCUR). She secured funding through the Office of Undergraduate Research (OUR) to present a poster at the spring national American Chemical Society (ACS) meeting in San Diego in March, where she won the division of inorganic chemistry’s undergraduate poster award (one of only five!).

The conference also allowed her to explore other areas of chemistry, and has helped her hone in on the field of bioinorganic chemistry for her Ph.D. She clearly is a chemist who is off to a fantastic research career!

Alison is a first-generation Chinese American, having lived all over the US before graduating high school in Utah. In addition to her studies and research, Alison works at the Utah Lions Eye Bank and as a waitress. In her spare time, she enjoys rock climbing, eating at Osteria Amore, and is helping to train a guide dog.

In addition to the Goldwater scholarship Alison has also received the Laya F. Kesner and Leon Watters Memorial Award, and the Undergraduate Research Scholarship from the University of Utah Department of Chemistry.

IF/THEN Ambassador

March 16, 2022

IF/THEN Ambassador

Janis Louie

IF/THEN is designed to activate a culture shift among young girls to open their eyes to STEM careers.

The august statuary of Washington, D.C. will soon include a University of Utah chemistry professor. A 3D-printed statue of Janis Louie will stand with 119 other statues of women in science, technology, engineering and math (STEM) in and around the National Mall from March 5-27.

The exhibit places Louie among the largest collection of statues of women ever assembled, according to the Smithsonian Institution, and celebrates the participants in the IF/THEN Ambassador program that is “designed to activate a culture shift among young girls to open their eyes to STEM careers,” according to the initiative’s website.

“I hope visitors feel inspired, encouraged and empowered,” says Louie. “For me, the exhibit is meant to show that STEM isn’t for one type of person, STEM is for everyone!”

Inspiring a Generation

The IF/THEN Ambassador Program is sponsored by Lyda Hill Philanthropies as part of the IF/THEN initiative. The initiative aims to “advance women in STEM by empowering current innovators and inspiring the next generation of pioneers.”

The Ambassadors program is a part of that initiative, and assembled high-profile women in STEM to act as role models for middle school-age girls. Ambassadors received media and communications training and then engaged in outreach work nationally.

Dr. Louie and family.

After selection in 2019, Louie traveled to a three-day conference with the other Ambassadors. “It was amazing!” she says. “It is the only conference I have ever been to that was 100% female scientists!”

It was a diverse group. “The featured women hail from a variety of fields,” she says, “from protecting wildlife, discovering galaxies and building YouTube’s platform to trying to cure cancer.”

Later, Louie appeared on an episode CBS’ Mission Unstoppable to draw connections between chemistry and the world around us. She also pitched in when another Ambassador’s summer STEM camp needed to go online with the onset of the COVID-19 pandemic.

“She asked a variety of the Ambassadors to present to the girls over Zoom, so that the STEM camp could still be impactful,” Louie says. “I was delighted to be one of the presenters!”

Meeting her statue

The process of creating the 120 statues was very different from the traditional sculpture techniques that created the hundreds of other statues in Washington, D.C. At the initial conference, Louie and the other Ambassadors each took a turn being digitally scanned in a booth with 89 cameras and 25 projectors so that the statues could later be 3D printed. (Learn more about the process of creating the exhibit here.)

When completed, the orange statues appeared in Dallas and New York City before the full exhibit was first unveiled in Dallas, Texas in May 2021. Washington, D.C. is the exhibition’s second stop.

Louie and her family traveled to Dallas to see her statue.

“It was surreal, in the best way!” she says, of meeting her doppelgänger.  “My children were able to see not only myself but a field of orange statues of women pioneers—and I was thanked by someone visiting the exhibit for making a difference.”

Meet the other Ambassadors featured in the exhibit here.

The Future of Space travel

Ming Hammond

For humanity to push the boundaries of space exploration, we’re going to need plants to come along for the ride. Not just spinach or potatoes, though—plants can do so much more than just feed us.

“There’s a lot of promise, potential and hope that we can use the tools developed in synthetic biology to solve problems.” says Chemistry Professor Ming Hammond, “not just that you would find in space, but where you have extreme limitation of resources.”

A synthetic garden.

Synthetic biology is a field that engineers biological systems. In this case, the team is looking at plants as potential bio-factories. Every organism naturally produces countless proteins as part of its biological function, so why not engineer a plant to produce, say, a needed medication or a polymer that could be useful in future long-term space exploration missions?

“The benefit is that you can take seeds with you,” Hammond said. “They’re very lightweight. They grow and gain biomass using the CO2 that we breathe out. And if those plants can produce proteins on demand—we know that plants are able to produce anti-viral and anti-cancer antibodies on a large scale.”

LED lights and USB camera.

Synthetic biology is already established on Earth. But translating that same technology to spaceflight requires different considerations. Hammond and her team encountered many of these constraints when adapting their experiment to operate within the small (10cm by 10cm) CubeSat enclosure.

For spaceflight, the team decided to engineer plants to change color as they produced the target protein, and monitor the progress with a camera. It’s an elegant and innovative solution, based on a previously published method, but adapted for the constraints of a cube in space.

Final assembly.

“We had to take something that worked beautifully in the most carefully controlled conditions,” Hammond said, “and get it to work under very harsh and challenging conditions inside the plant cube.”

The plant cube was designed with the forward vision of preparing for plant growth studies on the moon, and is a technology development step towards that goal.

The entire experiment took 10 days and appeared to show successful protein production. The results from the team, including collaborators from NASA Ames and International Space University, were published this year.

10x10cm experiment enclosure.

It takes a lot of time and effort to put equipment in space, and Hammond appreciates the many hours of work that the team has put in. “We are a small but dedicated group of volunteers,” she said. “People worked nonstop to fix last-minute things that came up before launch. I’m just really proud of the effort everyone’s put in.”

SpaceX Falcon 9 rocket.

Hammond and her family traveled to the NASA Kennedy Space Center to watch the Dec. 5, 2019 launch of her experiment, which was nestled within a SpaceX Falcon 9 rocket on a resupply mission to the International Space Station.

“At the launch of my experiment, we had a chance to see Bob Behnken and Doug Hurley, the two astronauts that flew the first manned SpaceX flight on May 30, 2020,” she said. “It was an amazing opportunity to share the launch with my son, (6 years old at the time), and other family members. Of all the things I’ve done in science this, for them, is the one that probably inspires the most interest and awe.”

David T. Chuljian

October 1, 2021

Describing himself as one of the world’s few “quantum dentists,” David T. Chuljian, PhD’84 in Chemistry, has an unusual perspective on dental decay rates, and particle-hole interactions.

Chuljian grew up in Port Townsend, Washington, until age 14. His father, G. T. “Chuck” Chuljian, had settled there in 1947 and opened a dental practice near the Keystone Ferry Terminal.

“Port Townsend was a very sleepy town in the 1960s. During summer, our day would be chores in the morning, then off on our bicycles and returning for dinner after spending the day with friends,” says Chuljian.

“We owned a small beach cabin on Discovery Bay, so many of our bike rides ended there to go fishing, swimming, or beach walking. Grade school was mostly at a one-room private school, with teachers of varying quality.”

“I had a couple of good teachers in elementary school, one of which was extremely varied in his knowledge and interests and he taught us a wild mix of things for science class – how airplanes work, astronomy, ecology, you name it. Math and science were fun for me after that,” says Chuljian.

“Like many dentists, my dad hoped at least one of us would go into dentistry, and it was assumed that all five of us kids would go on to college,” says Chuljian.

“But the local high school was not very academic – kids in town expected to work at the paper mill after graduation – so my parents sent us to a church-run high school, Auburn Academy, near Tacoma.”

After high school, Chuljian enrolled in Walla Walla College, a private Adventist school in College Place, Washington. He earned a bachelor’s degree in chemistry in 1978. During his senior year at Walla Walla he applied to medical school and to various graduate schools around the country.

“At the time, the chairman of our chem department, Barton Rippon, was collaborating with some folks doing bioengineering type stuff, and he encouraged me to apply at Utah,” says Chuljian.

Remarkably, Chuljian did not actually apply to the chemistry department for graduate school.

“In fact, I applied to Utah’s bioengineering program. But my application packet somehow wound up at the chemistry department, where Jack Simons saw it before forwarding it to bioengineering,” says Chuljian.

“Jack then called me and asked if I was interested in interviewing in Chemistry as well as Bioengineering, and said they’d pay for my plane ticket. This seemed like a great deal, so I wound up doing both interviews on the same trip,” says Chuljian.

“As it turned out, Jack’s theoretical chemistry work was extremely interesting, close to physics which I also enjoyed. So, in the end, I went with the chemistry department.” Jack Simons later served as Chuljian’s research advisor.

However, after two years of graduate school, Chuljian’s research wasn’t progressing as he wanted and tenure-track jobs around the country were extremely limited in number.

“I’m reasonably intelligent, but not Einstein, and I could tell I wasn’t really cut out for an academic position in theoretical chemistry,” says Chuljian.

So, in 1980, he applied to dental school at the University of Washington in Seattle and started that program in fall semester 1981.

“Since I already had more than three years towards my chemistry doctorate, I worked on both degrees in parallel, coming back to Utah during summers and Christmas vacations, and working remotely, mostly finishing up papers. Of course, this was all pre-Internet so there were some real challenges.”

“I remember most of my Utah research group: Ajit Banerjee, Deb Mukherjee, Judy Ozment, Gina Frey, Jim Jenkins, Ron Shephard, Rick Kendall, and Hugh Jenkins. I haven’t seen most of them since graduating, although in 2005 Jack had a reunion in Park City and I saw several of them there,” says Chuljian.

Chuljian took a sabbatical during his senior year in dental school to finish up and defend his doctorate thesis in December 1984, then returned to Washington and finished up his clinical requirements and dental licensing exam in August 1985.

That same year, Chuljian moved back to Port Townsend and began working with his father as an associate in the dental practice. He later purchased the office in 1987 and his father retired in 1990.

“It was a standard small-town practice, doing everything including orthodontics and surgery since no specialists were available nearby. When I retired in 2017, I sold the practice which represented 70 years of family-owned dentistry, the oldest business in town I think,” says Chuljian.

Chuljian stays busy with a range of activities and interests, including forestry, flying, and rescue care of birds, in particular parrots. Over the years, Chuljian has rescued and cared for two African Grays, a couple of Amazons, several conures, and three Pionus species of parrots.

Today, Chuljian still resides in Port Townsend, which is no longer a sleepy bywater but has a vibrant arts and boating community. His typical day might include several hours working in his forest tracts, irrigating newly planted trees or removing invasive species, or milling lumber for the local animal shelter’s building projects. Or it could be a 10-hour day drilling and filling at the local public health dental clinic. He enjoys mountain biking, but when he qualified for Medicare he upgraded to an eBike!
