About Me

I am an Instructor in 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).

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

Research Interests

Arithmetic groups, algebraic groups, locally symmetric spaces, and their connections to number theory and geometry. Homogeneous dynamics, harmonic analysis, geometric group theory.
