I am an Associate Professor in the Math Department at the University of Washington, Seattle.

I can be reached via [first 8 letters of last name]@uw.edu

My main field of research is Analysis. I like questions combining PDEs, Spectral Theory, Harmonic Analysis

and all sorts of applications. My research is supported by NSF DMS-2123224 and the Sloan Foundation. CV
