My research is currently supported by the National Science Foundation (under Awards 1237235, 1421770, 1524052, 1565387), the AFOSR, DARPA (BRASS program), and a Google Faculty Research Award. I have previously been supported by IARPA, an Alfred P. Sloan Research Fellowship, and NSF Awards 1054172, 1551249 .
I completed a Ph.D. at Cornell University in August 2008, under the guidance of Andrew Myers. Prior to graduate school, I spent several years working as a consultant and contractor. I received a B.Sc.(Hons) and B.A. from Victoria University of Wellington, in Wellington, New Zealand. My wife, Kiran Gajwani, is a Lecturer/Advisor in the Economics Department at Harvard.
