About Me

I am an Instructor of Mathematics at Brandeis University. In the academic year 2020-2021, I was a postdoctoral fellow at the Einstein Institute of Mathematics of the Hebrew University of Jerusalem, hosted by Elon Lindenstrauss and supported by a Zuckerman postdoctoral fellowship. I am currently applying for jobs (Fall 2022).

Together with Dmitry Kleinbock, Han Li, and Felipe Ramirez, we organize the online New England Dynamics and Number Theory seminar which meets on (some) Thursdays 12:15pm-1:15pm.

I received my Ph.D. in Mathematics from Yale University in 2019. I am fortunate to have had Professors Gregory Margulis (Yale University) and Emmanuel Breuillard (University of Cambridge) as advisers.

I am primarily interested in arithmetic groups, and their generalizations, in particular, connections to number theory and geometry.
