My main research interests are in computational aspects of economics and game theory, design and analysis of algorithms, and mathematical programming. Currently, I am working on designing fast algorithms for computing competitive equilibria with applications to fair division problems. I received my BTech and PhD in Computer Science from IIT-Bombay. Later, I was a postdoc in Algorithms and Randomness Center at Georgia Tech, and in Algorithms and Complexity group at Max-Planck-Institut für Informatik, Saarbrücken. For more information, please see my CV.
My research is funded by the NSF CRII Award and the NSF CAREER Award.
