I am a Ralph Boas Assistant Professor at Northwestern University.
In 2015, I finished my Ph.D. at Universite de Montreal under the supervision of Iosif Polterovich.

I am interested in geometric spectral theory. More precisely, I study growth and nodal sets of
eigenfunctions of elliptic operators on Riemannian manifolds.

This quarter (Winter), I teach MAT224. You can get more details through Canvas .
In Summer 2015, I taught the course MAT1000, Analysis I at Universite de Montreal
Here is a summary of my teaching evaluations and CTECs.
