Brief Introduction:
I am a Research Scientist at Google Research NYC. My main research interests are social content recommendation and mining and scalable structured data extraction and processing. Previously, I also worked on database usability and data integration. Before Google, I was with Yahoo! Research New York, from July 2007 to September 2010. While there, I was mainly involved in two projects: Purple SOX and Royal Jelly. Before Yahoo!, I graduated from the Database Group at the University of Michigan, Ann Arbor, with a Ph.D. degree in Computer Science and Engineering. My advisor is Prof. H. V. Jagadish.
I am a devoted Michigan Wolverines fan. I have followed all the games since the Michigan-OSU game in the 2003 season. Things I read: New Yorker, Economist, New York Times, Wall Street Journal.
