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 CU 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 91��ý, 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 91��ý,��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.
