About
I am an Associate Professor in the computer science department at the University of Chicago.
Previously, I held research positions at the University of California at Berkeley, advised by Umesh Vazirani, and in QuICS, at the University of Maryland/NIST.
I received my Ph.D. in computer science in the Department of Computer and Mathematical Sciences and the Institute for Quantum Information and Matter at Caltech, co-advised by Alexei Kitaev and Chris Umans.
