My research is in

I am a Research Instructor (postdoc) at Princeton University and the Institute for Advanced Study. Before coming to Princeton, I finished my PhD in Computer Science at Carnegie Mellon University where I was advised by Manuel Blum and Anupam Gupta. Earlier, I got a master's degree from University of Waterloo and a bachelor's degree from Indian Institute of Technology, Delhi, in Computer Science.
