I am currently a Research Scientist at Google NY. I have been PC Chair or Area Chair of several conferences in the field of Machine Learning/Artificial Intelligence (e.g., COLT, ALT, NIPS, ICML, IJCAI). I held a Research Director position at INRIA (France), and visiting positions at a number of institutions, including UC Santa Cruz, Microsoft Research, and Technion (Israel). My current research interests include online learning with partial information, active learning, online clustering, and applications thereof. More information can be found at my homepage.
