Principal Investigator 

Amy L. Brewster, Ph.D.

​I earned my B.S. in Biology from the University of Puerto Rico at Cayey, my Ph.D. from UC Irvine, and completed my postdoc at Baylor College of Medicine in Houston. I’m now an Associate Professor at SMU, where I love combining research with mentoring the amazing students in my lab. When I’m not working, I’m usually out on the trails with my golden retriever, Beto, my top hiking buddy and unofficial lab mascot.
