Seraphina Eun Bi Lee

I am a second year graduate student in the Department of Mathematics at the University of Chicago, advised by Benson Farb. Most recently, I've been thinking about the topology of 4-manifolds and their mapping class groups. Previously, I was an undergraduate at Cornell University.
