Student Spotlight – Mary Doan

I am a graduate student in the laboratory of Dr. Michael Teitell, M.D., Ph.D., where my research focuses on metabolic regulation and its influence on cell fate, particularly how distinct metabolic pathway usage shapes cell type diversity. 

Exciting research project or any highlights in your lab

One of my lab’s main focuses is mitochondrial metabolism. In my area, we were among the first labs to show that metabolism can actively drive stem cell fate decisions, and my current projects continue to build on that work. We also pursue innovative studies on mitochondria transfer, revealing how the exchange of mitochondria can reprogram the metabolic state of recipient cells and influence cancer growth.

How did you decide on your focus of research?

I was fortunate to have an enriching undergraduate research experience with my PI, Dr. Nathaniel Snyder, whose hands-on mentorship shaped my interest in metabolism. Under his guidance, I learned to quantify and analyze nutrient fluxes and metabolite levels across a wide range of specimens, equipping me to contribute to projects and collaborate with incredible scientists through cross-institutional studies. What excites me most is being among the first to uncover new mechanistic insights—whether advancing our fundamental scientific framework or improving lives. Because metabolism is so deeply intertwined with all cellular functions, there remains much to unravel about its regulation to fully understand normal and pathological physiology. 

What brought you to UCLA?

Honestly, I wanted to experience the west coast in all its glory – what better place than Los Angeles? 

Do you have a personal motto?

YOLO or NOLO, you only live once so is it a yes or no? 

Do you have any hobbies outside of the lab?

I am an avid foodie with 7+ years as a Yelp Gold Elite. Outside of that, I rock climb, frequently run along the beaches of the PCH, and am currently battling the treacherous journey of golf with my friend Jemmie.
