I am an Associate Professor at the University of Wisconsin-Madison. I received my Ph.D. from Princeton University under the direction of Peter Sarnak.
I am an analytic number theorist. I am particularly interested in properties of arithmetic manifolds such as their cohomology, and how much their eigenfunctions can concentrate.
I organized the conference Harmonic Analysis and Symmetric Spaces 2021, online October 27-29.
