Broadly, I am interested in theoretical problems related to the theme `Optimization Under Uncertainty'. More particularly, I am currently working on discrete optimization problems and my uncertainty models are inspired from areas such as Online & Approximation Algorithms, Machine Learning Theory, Algorithmic Game Theory, and Stochastic Modeling.

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 under the supervision of Prof Manuel Blum and Prof Anupam Gupta. Earlier, I obtained a master's degree from University of Waterloo and a bachelor's degree from Indian Institute of Technology, Delhi, in Computer Science.
