About Me

I am a research scientist at Intel Labs Pittsburgh. I received my Ph.D. under the supervision of Prof. Todd C. Mowry and Prof. Anastasia Ailamaki in computer science from Carnegie Mellon University in December 2005, and my B.E. and M.E. in 1997 and 1999 from Department of Computer Science and Technology in Tsinghua University, Beijing, China. My research interests include database systems, computer architectures, operating systems and other software systems. My Ph.D. work focused on redesigning data structures and algorithms in relational database systems in light of modern computer architecture features such as CPU cache prefetching. At Intel Labs Pittsburgh, I have been working on exploiting modern hardware features, including many-core processors, CPU caches, and flash based devices, for software correctness, performance and power efficiency, and supporting data-intensive and compute-intensive applications on data-center-scale clusters. I am currently working on the Hi-Spade and LBA projects.

My Life

My wife, Qin Jin, and I like to listen to music, see movies, and play badminton, table tennis, and volleyball. We like travel very much. Here are our photos.
