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, anomaly detection and causal discovery .

I am always looking for highly motivated students to join our group. Please feel free to contact me, if you are interested in our work and willing to publish top-tier papers.
