# Gus Schrader

I'm a graduate student in the math department at UC Berkeley. My advisor is Nicolai Reshetikhin.
At the moment, my research is focused on quantum groups, quantum character varieties, cluster algebras and integrable systems. I'm also interested in applications of theta functions in mathematical physics and algebraic geometry.
