About Me
I am an Assistant Professor in the Darden School of Business at the University of Virginia. Prior to this, I was a postdoc at Microsoft Research New York City, a computer science PhD student
at Duke University advised by
Vince Conitzer, and an undergraduate at the University of Auckland, New Zealand
.
I am interested in various topics at the intersection of computer science and economics including computational social choice, fair division, resource allocation, and prediction mechanisms.

Note: Nisarg and I gave
a tutorial on fair division at EC 2019, AAAI 2020 and AAMAS 2020. The most current version of the slides can be found here.
