Welcome
Hello! Welcome to my homepage. I am a faculty member of the computer science department in UCSB. Prior joining UCSB, I was a scientist with Amazon AI in Palo Alto. Even before that I was with the Machine Learning Department in Carnegie Mellon University and had the pleasure of being jointly advised by Stephen Fienberg, Alex Smola, Ryan Tibshirani and Jing Lei.
Over the years I have worked on a diverse set of problems in the broad area of statistical machine learning, e.g., trend filtering, differential privacy, subspace clustering, large-scale learning / optimization, bandits / reinforcement learning, just to name a few. Check out my publication page for details. My most recent quests include making differential privacy practical and developing a statistical foundation for off-policy reinforcement learning.
