I am a Ph.D. student in pure mathematics in the Department of Mathematics at the University of Michigan in Ann Arbor. My advisor is Lizhen Ji. I started here in September 2015. I obtained my B.S. in mathematics from Caltech in June 2015. Before that, I lived in Cary, NC, and before that, I lived in Rochester, NY.
Here is my CV.
I am interested in geometry and topology. My favorite types of questions are those in which both geometry and topology play a major role. Specifically, I have been studying Teichmüller spaces and moduli spaces of Riemann surfaces and connections to other geometric objects, such as symmetric spaces, and generalizations. I am also interested in differential geometry, mapping class groups, and other related objects. Occasionally, I am interested in applications to other fields (not necessarily pure mathematics).

I am not teaching during the 2016-2017 school year. However, I am available to tutor students in many of the undergraduate mathematics courses at U of M, as well as younger students who can come to U of M's central campus. Feel free to email me if interested.
