I am a sixth-year PhD candidate in computer science at the University of Pennsylvania, where I am a member of the database research group and the ORCHESTRA project. My research interests include collaborative data sharing, data provenance, incomplete and probabilistic databases, query optimization, semistructured data, and streaming data processing. I am co-advised by Zack Ives and Val Tannen. Here is my curriculum vitae.

News: I'm joining the Department of Computer Science at UC Davis in Fall 2009 as an Assistant Professor.
