I am currently a Research Assistant Professor with Department of Computing at The Hong Kong Polytechnic University (eligible to hire/supervise Ph.D./Postdoc/RA). I successfully defended my Ph.D. degree in Dec. 2020 at the same university, supervised by Prof. Song Guo (now HKUST). Prior to that, I received my M.E. degree (2015) from Waseda University, Japan, supervised by Prof. Takayuki Furuzuki, and B.E. degree (2013) from Sichuan University, China, all in Computer Science. From 2021 to 2022, I was an Associate Professor with School of Computing and Artificial Intelligence, SWUFE, China, and from 2019 to 2020, I was a Visiting Ph.D./Researcher with University of Sydney, Australia, supervised by Prof. Dacheng Tao (now NTU). Before I did my Ph.D., I spent 2 years in investment banking after Waseda.

I am generally interested in Low-Shot AI: learning/modeling with Limited Resources in terms of Data (), Computing Capability (), and some of their derivative Applications () that are beneficial from theory to practice. Our topics include zero/few-shot learning, federated/distributed learning, model compression, representation learning, and lightweight deployment/training of foundation models. Our works are published in prestigious venues, including AAAI, CVPR, IJCAI, ICML, ICLR, MM, ATC, ICME, ICASSP, ICDCS, TNNLS, TPAMI, TMM, TC, NN, etc. As the Principal Investigator (PI), I have secured several external grants like 2 × General Research Funds (GRF) from Hong Kong RGC, the Young Scientists Fund from NSFC, and the Fundamental Research Funds for the Central Universities. If you are interested in any of these topics, please feel free to e-mail me!

I am currently serving as Associate Editor for IEEE Open Journal of the Computer Society (IF=5.9) and Guest Editor for IEEE Transactions on Computational Social Systems (IF=5.0). I have served as Publicity Chair for SRDS 2022 and Track Chair for VTC 2024 Fall, and have served as Area Chair and/or Session Chair for prestigious conferences like ICML, ACM-MM, IJCAI, ICME, and VTC. I also regularly serve as PC Member and/or Reviewer for AAAI, CVPR, NeurIPS, ACM-MM, ICML, ICLR, ICCV, ICME, ICASSP, ECCV, etc., and Reviewer for a series of IEEE transactions and journals like TNNLS, TMM, TMC, TKDE, TCSVT, TSUSC, JSAC, IoT-J, etc. I am a Reviewer for the General Program and the Young Scientists Fund of National Natural Science Foundation of China (NSFC). I am a member of IEEE and CCF. I was the recipient of the Hong Kong PhD Fellowship Scheme (HKPFS) supported by Hong Kong RGC in 2017 (with gratefulness 💝).
