Chemical and Biological Engineering PhD student Erin Dunphy has won the prestigious International Centre for Diffraction Data’s Ludo Frevel Crystallography Scholarship, which recognizes research promise in the field of crystallography. Crystallography, the science of figuring out how atoms are arranged inside a solid material, has been essential in developing X-ray, electron and neutron diffraction methods to reveal the atomic structure of materials.

Tell me about your research

My research examines how polymers (long-chain molecules) and hydrocarbon (molecules made of hydrogen and carbon, such as fuels) attach to the surface of Ruthenium-based catalysts, which are used to speed up chemical reactions. Understanding this interaction is critical to improving catalytic processes for polymer upcycling, an innovative approach for converting plastic wastes into valuable products, such as jet fuels. By studying these interactions at the atomic level, we gain insight into how the materials bind and react, helping guide the design of more efficient catalysts.

What does receiving the Ludo Frevel Crystallography Scholarship Award mean to you?

Receiving the Ludo Frevel Crystallography Scholarship is a great honor that marks a milestone for my academic career. It's exciting that my research inspires others and reminds me that fundamental research is critical to the development of new technologies.

How will this scholarship support your research or academic goals?

Receiving this scholarship reinforces my commitment to tackling complex scientific challenges by developing techniques that deliver real-world solutions. I aim to continue pushing boundaries at the intersection of fundamental science and technology development.

What drew you to crystallography as a research focus?

My first experience with advanced crystallography was during a science undergraduate laboratory internship when I worked at the National Synchrotron Light Source II. While there, I realized that materials optimization, improving a material’s properties so it performs as well as possible for a specific application, is often the key bottleneck limiting progress in energy and infrastructure technologies.

What are you most excited to work on?

I am excited to finish my �鶹��Ѱ��Boulder research and to defend my thesis in June. I am performing my final single-crystal diffraction studies at the European Synchrotron Radiation Facility in Grenoble, France. This technique allows scientists to map the atomic structure at the crystal interface.

For these experiments, I designed a custom reaction chamber that can operate at temperatures up to 250°C and pressures of 15 bar, allowing us to study materials under realistic working conditions. I also developed specialized software that processes and analyzes the data in real time.

What are your future research or career goals?

My sights are set on integrating renewable energy onto an industrial scale. Plastics recycling using catalysis offers a route to sustainable fuel generation which is part of creating a circular energy infrastructure. Ultimately using multiple forms of green energy generation (solar, wind) is all a part of the renewable energy infrastructure.

I hope to work with industry professionals to optimize new technologies and streamline deployment onto national and international scales.

How do you hope your work will contribute to the field?

My research looks at how molecules or atoms (called adsorbates) attach to the surface of a single crystal under realistic conditions for thermal catalysis. I hope my work encourages other researchers to study surfaces in environments that go beyond the extremely clean, ultra-high vacuum conditions typically used to more real-world operating conditions. Ultimately, my work helps expand surface science to investigate materials in contact with liquids, oils and membranes under practical pressures and temperatures, making the findings more relevant to real-world applications such as in thermal catalysis.

Dunphy's research involves studying interactions at the atomic level to design more efficient catalysts for polymer upcycling, an innovative approach for converting plastic wastes into valuable products, such as jet fuels.

Alumnus establishes scholarship for students involved with ‘oSTEM’

From right, Thad Sauvain with his husband, Carl, in front of the Bernese Alps near Murren, Switzerland, in May 2025.

Thad Sauvain (ChemEngr’91) grew up in Colorado Springs in the 1980s, when the climate was largely anti-LGBTQ+ and conservative ministries such as Focus on the Family, headquartered just a few miles from his home, were actively opposing anti-discrimination policies.

Sauvain is part of the LGBTQ+ community, but during that period, he mostly kept that part of himself hidden.

“It was my transition to �鶹��Ѱ��Boulder to get a BS in chemical engineering that allowed both parts of me—as an engineer and as a gay individual—to grow and thrive,” he said.

Sauvain recently established a legacy endowment in his estate plan to fund undergraduate scholarships for �鶹��Ѱ��Boulder chemical and mechanical engineering majors, with preference given to students who demonstrate a commitment to the LGBTQ+ community through involvement in Out in STEM (oSTEM) or similar college programs.

Each year the endowment supports one student for four years of their college education.

“There’s a need to support students whose college funding may depend on families who are not accepting and who may be forced to choose between that funding and living authentically,” Sauvain said. “I want to support engineering students who struggle to thrive as LGBTQ+ individuals. I hope the endowment enables them to be their true selves while contributing to society as successful engineers.”

Thriving at CU

Sauvain studied chemical engineering at �鶹��Ѱ��Boulder and was later recruited to join Chevron as a process engineer. He recently retired following a 33-year career with the company and is a member of the Chemical and Biological Engineering Advisory Board.

“My engineering degree prepared me for my career and helped me build the connections that launched it,” he said.

Three years after starting his role at Chevron, Sauvain became involved in the company’s campus recruiting for engineers, a role that eventually grew into his work as a liaison for Chevron’s gifts, donations and funding.

In the early 2000s, he helped establish a Chevron scholarship for those involved in �鶹��Ѱ��Boulder’s LGBTQ+ community, similar to scholarships for other diversity organizations in place at the time, during “a time when it was not the norm.”

Thad Sauvain shortly after graduating from �鶹��Ѱ��Boulder and
starting his career with Chevron in 1991.

“Some responded negatively to this new scholarship,” he said. “But Chevron’s senior management remained steadfast in its support of the new scholarship as it aligned with the company’s values and The Chevron Way.

“Every time I tell people that I went to �鶹��Ѱ��Boulder, I feel a deep sense of pride,” he added. “Even back in the 1980s, it was a shining beacon of acceptance. I've seen that grow and broaden over the years, and I am very proud to be part of the �鶹��Ѱ��community and a graduate of �鶹��Ѱ��Boulder's College of Engineering.”

Looking ahead

Sauvain recently met with oSTEM students to talk about the climate for today’s LGBTQ+ community and its historical context.

“I told them that in 1998 when Matthew Shepard was killed, you could not be out and visible, gay, transgender, anything. And though it seems like we're taking several steps backwards now, it has gotten better since then, and long term, I fully believe that it will again get better.”

Sauvain emphasized the College of Engineering’s strong support for the LGBTQ community, noting that he has seen this commitment firsthand through his work with Chevron, his service on the Engineering Advisory Board, and now through the creation of this endowment.

“Being part of the LGBTQ+ community is only one aspect of my being, just as my training as a chemical engineer is another,” he said. “Both have enriched my life in ways I never expected. My chemical engineering degree from �鶹��Ѱ��enabled me to build a successful 35-year career in an industry not necessarily known for being accepting of the LGBTQ+ community, during which I came out to everyone in my life. I attribute my college years at �鶹��Ѱ��with giving me the confidence to become my true self, both as an LGBTQ individual and as a chemical engineer, and I hope that this endowment will help others following a similar path.”

Wyatt Shields receives Grubstake Award to advance treatment toward clinical use Susan Glairon Thu, 01/22/2026 - 14:06

Assistant Professor Wyatt Shields

High-grade serous carcinoma is the deadliest form of ovarian cancer, and while a drug called olaparib can help prevent the cancer from returning, it often causes serious side effects. To address this challenge, Wyatt Shields, assistant professor in �鶹��Ѱ��Boulder’s Department of Chemical and Biological Engineering, Benjamin Bitler, associate professor in the �鶹��Ѱ��Anschutz Division of Reproductive Sciences and �鶹��Ѱ��PhD Student Courtney Bailey have developed a new way to deliver the drug more safely. Their approach uses tiny, biodegradable particles carried by immune cells to deliver treatment directly to tumors, helping reduce harmful effects on the rest of the body. Funding totaling $300,000 from the Gates Institute at University of Colorado Anschutz, in partnership with �鶹��Ѱ��Anschutz Innovations, will support the next steps to move this technology closer to clinical use.

Double major, triple honors: Ethan Coleman earns academic, research and outstanding student awards

Double major, triple honors: Ethan Coleman earns academic, research and outstanding student awards Susan Glairon Mon, 12/01/2025 - 03:28

Susan Glairon

Ethan Coleman presents his research at the 2024 AIChE annual student conference, held in San Diego.

When Ethan Coleman attends winter graduation, he’ll receive not one, but two �鶹��Ѱ��Engineering degrees. He’ll also take home three of the College of Engineering and Applied Science fall undergraduate awards.

Coleman, who is double majoring in Chemical and Biological Engineering (ChBE) and Applied Mathematics, suspected he might receive the Research Award. But what he didn’t guess was that he’d also be recognized with the Academic Engagement Award as well as the honor he’s most proud of—Outstanding Undergraduate of the College.

“It feels more holistic,” Coleman said of his third award. “I’m being recognized for more than just good grades and research.”

Those recognitions reflect his work as a teaching assistant for six classes; his strong academic performance—including three graduate-level classes—and his research, where he served as first author on two papers stemming from his undergraduate thesis. It also reflects his time spent as a ChBE student ambassador as well as participating in the Global Engineering Residential Academic Program.

Mountains calling

Coleman spent his high school years in San Antonio, Texas. After visiting Colorado a few times, he decided on �鶹��Ѱ��Boulder, drawn by his love of hiking.

He majored in chemical and biological engineering because he enjoyed math and chemistry. Interested in numerics, Coleman also added an applied math double major with ChBE.

“I enjoy taking classes, doing research and teaching,” Coleman said. “Sometimes it becomes overwhelming, but for the most part, I don't mind the work. I definitely wouldn't have gone as far as I have if I did.”

Coleman completed his double major in nine semesters, with help from the AP credits in calculus and chemistry he earned in high school. He’s not sure how he fit everything in, including his passion for hiking.

“I don't really have a system,” Coleman said. “I'm a night owl. I'll do something fun in the afternoon, and then knock out some homework at night.”

And when Coleman wasn’t studying, he could often be found on one of Colorado's trails. Two years ago Coleman hiked all 486 miles of the Colorado Trail in a month. He and a companion aimed for 20 miles a day, but on some days they pushed to 30 to make up for weather delays. Every week or so, they hitchhiked into town to pick up a resupply box they’d mailed themselves and to sleep in a real bed.

Coleman and a companion hiked the entire 486 miles of the Colorado trail in August 2024.

Road to research

As a junior, Coleman took a graduate-level transport class taught by Assistant Professor Ankur Gupta while carrying a 19-credit courseload—well above the typical 15 credits.

“That class was fun, but it was also hard,” Coleman said. “Having a professor who was supportive throughout was awesome. I ended up joining his lab because I really appreciated him as an instructor.”

Gupta's feelings were mutual.

“The recognitions are all very well-deserved for Ethan,” Gupta said. “He took two courses with me, including a graduate-level course where he was among the highest scorers, even as a junior.”

Over the course of his time at �鶹��Ѱ��Boulder, Coleman was a learning assistant for six classes, including multivarious calculus and other teaching positions in applied math and ChBE.

Coleman has worked in Gupta’s Laboratory of Interfaces, Flow and Electrokinetics (LIFE) for two years. For the first few months he worked under a postdoctoral researcher, but then asked to head his own projects.

“Ankur was totally supportive,” Coleman said. “I wasn’t totally ready, with only three months of research experience, but Ankur said ‘If you get stuck, let me know.’ He did it in a way that was very conducive to me learning. He was very intentional about helping me grow into a good researcher.”

Coleman’s favorite research project is one he came up with himself: using microparticles that react to chemical gradients to move bacteria inside biofilms—clusters of bacteria joined by sticky polymers that are hard to remove. His goal: to discover a way to clean biofilms from porous materials.

“Ethan has been very creative and productive, on par with a graduate student,” Gupta added. “I am very excited for him and eager to follow his career, and wish him the very best.”

Looking ahead

Coleman plans to continue working in the LIFE lab for a few months after graduation. He’s applying to graduate schools to pursue a PhD in chemical and biological engineering and plans to become a professor. He’s specifically looking for labs that perform the type of biological research he currently pursues.

The recognitions reflect Coleman's work as a teaching assistant for six classes; his strong academic performance—including three graduate-level classes— and his research, where he served as first author on two papers stemming from his undergraduate thesis. It also reflects his time spent as a ChBE student ambassador.
