Assistant Professor Department of Computer Science


Dr. Han is currently an Assistant Professor of Computer Science at Hong Kong Baptist University, and a Visiting Scientist at RIKEN Center for Advanced Intelligence Project (RIKEN AIP), hosted by Masashi Sugiyama. He was a Postdoc Fellow at RIKEN AIP (2019-2020), advised by Masashi Sugiyama. He received his Ph.D. degree in Computer Science from University of Technology Sydney (2015-2019), advised by Ivor W. Tsang and Ling Chen. During 2018-2019, he was a Research Intern with the AI Residency Program at RIKEN AIP, working on robust deep learning projects with Masashi Sugiyama, Gang Niu and Mingyuan Zhou. He has served as area chairs of NeurIPS'20 and ICLR'21, and program committes of ICML, AISTATS, UAI, AAAI, IJCAI and ACML. He received the RIKEN BAIHO Award (2019), RGC Early Career Scheme (2020) and NSFC Young Scientists Fund (2020).
