Redirecting to new website: … 

I’m currently a Research Fellow at the Simons Institute for the Theory of Computing, until May 2018. I am delighted to be a part of two semester-long programs: Bridging Continuous and Discrete Optimization and Real-Time Decision Making. Prior to this, I obtained a doctoral degree in Operations Research from MIT, and was lucky to have Michel Goemans and Patrick Jaillet as my thesis advisors. For my bachelors (and a joint masters), I majored in Computer Science and Engineering (CSE) at IIT Delhi. My research interests are broadly in

  • combinatorial, convex and robust optimization with applications in online learning and data-driven decision-making under partial information (here’s a LIDS article about some of this work),
  • optimization with applications in pricing and revenue management, inventory routing and machine learning (here’s a Huffington Post article about some of our work on pricing),
  • strategic behavior, fairness and “unintended” bias in decisions (a growing list of problems identified in current learning and optimization methods and the data they use)
