Yuzhou Joey Zou (邹雨舟)

Boas Assistant Professor, Department of Mathematics, Northwestern University

Starting August 15, 2025, I will be moving to Oakland University as an Assistant Professor.
My new webpage will be here: https://joey-zou.github.io

I am a Boas Assistant Professor at Northwestern University working with Jared Wunsch. I am interested in microlocal analysis, inverse problems, PDE, and mathematical physics.

Previously (from 2021-2022) I was a postdoc at UC Santa Cruz working with François Monard.

I obtained my Ph.D. in August 2021 from Stanford University under the supervision of András Vasy.

Here is my CV.
