CV

I am an H.C. Wang Assistant Professor in the Department of Mathematics at Cornell University. My interests include classical, equivariant, and motivic stable homotopy theory, algebraic K-theory and trace methods, and equivariant algebra.

I also co-organize the Electronic Computational Homotopy Theory online research community with Dan Isaksen, Hana Jia Kong, and Guchuan Li.
