I graduated and joined Microsoft Research in the summer of 2015. (Here is my homepage at Microsoft Research.)

From 2010 to 2015, I was a Ph.D. student in Computer Sciences Department at the University of Wisconsin-Madison. My research interest lies in database management systems, and I was very fortunate to be advised by Prof. Jeffrey Naughton. Before coming to Madison, I obtained my M.S. and B.S. degree in Computer Science, both from Fudan University, in 2010 and 2007, respectively.
