About Me

I am a sixth year student in mathematics at the University of Illinois at Urbana-Champaign. I completed my BS in mathematics in 2013 at Carnegie Mellon University. I passed my preliminary exam in August 2015 and am now working on my thesis research.

I study tame geometry, and dependent expansions of o-minimal structures. In particular, I have recently been interested in questions around distality.
