Xinyi Li 李欣意
Assistant Professor at Beijing International Center for Mathematical Research, Peking University.
My main research interests are probability theory and statistical physics.
I was an L. E. Dickson instructor at the University of Chicago from 2016 to 2019.
I received my Ph.D. from ETH Zurich. My advisor was Professor Alain-Sol Sznitman.
