About:

I am an NSF postdoc at UC Berkeley. During the Spring semester of 2019, I was a postdoc at MSRI.

My research is in algebraic geometry. Among other things, I am interested in birational geometry, Brauer groups, Calabi-Yau varieties, and derived categories, particularly in positive characteristic.

I am a co-organizer of the Berkeley arithmetic geometry and number theory seminar.
