I am a postdoctoral scientist in the machine learning department, NEC Laboratories America, INC in Princeton, New Jersey. My research interests include information retrieval, machine learning and signal processing.

I received my Ph.D from Computer Science Department at Rutgers University in 2007, under supervision of professor Paul B. Kantor. I received my B.E. from School of Information Science and Techonology at Tsinghua University in 1997.
