I am now an assistant professor at School of Computer Science and Technology, Beijing Institute of Technology. Before that, I received my Ph.D. degree in Computer Science and Technology from Tsinghua University, under the supervision of Prof. Shaoping Ma and Prof. Yiqun Liu.

My major research interests are Information Retrieval and Natural Language Processing. I am looking for self-motivated students to work with me. Feel free to email me if you have interests.
