I am a Ph.D candidate in the Department of Computer Science at the University of Illinois, Urbana-Champaign (UIUC). I expect to graduate May 2012.

My research advisor is Prof. Eyal Amir. My thesis study is about lifted inference algorithms for (relational) graphical models.

Research Interest

I am interested in general topics in Artificial Intelligence.

The topics include the Lifted Inference with Probabilistic Graphical Models, Reasoning in Large-scale Cypber-Physical Systems (CPSs),Robot Planning, Image & Video Matching Algorithm, and Automated Reasoning.

News!

I was named for "UIUC CS/AI Award for Graduate Students", Beckman Institute, 2009
