I am currently an Associate Professor with School of Information and Communication Engineering (SICE), Beijing University of Posts and Telecommunications (BUPT). My researches are developing models and algorithms to learn with high dimensional data. My research interests include subspace/manifold clustering, sparse/low-rank model, dictionary sorting, matrix completion, and their applications in computer vision and pattern recognition.

I visited the Johns Hopkins Mathematical Institute for Data Science from Dec. 2019 to Feb. 2020, the Vision, Dynamics and Learning lab, Johns Hopkins University, from Dec. 2012 to Nov. 2013, both with Dr. Rene Vidal, and visited at Visual Computing group, Microsoft Research Asian (MSRA), as a Visiting Researcher, from July 2011 to April 2012, with Dr. Zhouchen Lin and Yi Ma.

I received PhD in Signal and Information Processing from BUPT in Dec. 2007, supervised by Prof. Jun Guo, and received B.E. from Jilin University (JLU) in July 2002.
