Siyi Zhang

I am a Kenna Visiting Instructor at University of Notre Dame. My research interests include conformal geometry and geometric analysis.

I received my PhD at Princeton University in 2019. My advisor is S.-Y. A. Chang.

My email is szhang25@nd.edu.

Before graduate school at Princeton, I was an undergraduate math major at Peking University.
