Sudeep Raja is a Doctoral student in the IEOR Department at Columbia University, advised by Prof. Shipra Agrawal. His research interests are Sequential decision-making under uncertainty, specifically online convex optimization, multi-armed bandits and reinforcement learning of structured MDPs. He aims to design efficient algorithms with provable guarantees for online decision-making. Sudeep holds a Master of Science in Computer Science from the University of Massachusetts Amherst and a Bachelor of Technology in Computer Science and Engineering from the Indian Institute of Technology Kharagpur.

Quotes

Don't worry about the overall importance of the problem; work on it if it looks interesting. I think there's a sufficient correlation between interest and importance. — David Blackwell
