Background

About

About

I am currently an assistant professor in Institute of Computing Technology, Chinese Academy of Sciences(ICT, CAS). Before joining ICT, I obtained my Ph.D. degree in University of Chinese Academy of Sciences supervised by Prof. Jingping Bi. The thesis is avaliable HERE. Previously I conducted one year visiting at DMAL, Nanyang Technological University under the supervision of Prof. Gao Cong. My research interest lies in time series analysis, spatio-temporal data mining, graph mining and deep learning. The research projects that I have conducted span across the areas of natural language processing, trajectory analysis and anomaly detection.
