Research & SERVICE
My research interests are in distributionally robust optimization, worst case probability bounds, learning and applications in health care. I have also worked on problems at the intersection of machine learning and game theory- more specifically on topic models, multi-armed bandit algorithms and mechanisms, crowdsourcing.
