Biography
I grew up in Aurora, Colorado, and spent time at the University of Colorado before coming to Yale. I am interested broadly in voltage-gated ion channels as they relate to both normal function and disease. Outside of academics, I love playing and watching all kinds of sports, exploring breweries, and finding new places to eat.
