Stefan Steinerberger

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]

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
