About me

Welcome! I am currently a Research Assistant Professor in the Department of Electrical and Electronic Engineering (EEE), The Hong Kong Polytechnic University (香港理工大学, PolyU). I am also working in the JC STEM Lab of Machine Learning and Computer Vision with Prof. CHAU Lap Pui. My research interests include Visual Information Processing, Egocentric Vision, Embodied Cognition, and Multimedia Forensics.

I received BEng in Electronic and Information Engineering and MEng in Signal and Information Processing from Northwestern Polytechnical University (西北工业大学, NPU), China, and earned PhD in the School of Electrical and Electronic Engineering (EEE) from Nanyang Technological University (南洋理工大学，NTU), Singapore, in 2021, supervised by Dr. CHAU Lap Pui, who worked as an A/P at NTU (till 2022) and is currently a Prof. at PolyU.

Prior to joining PolyU, I worked as a Research Fellow in EEE, NTU, until March 2023 with PI A/P YAP Kim Hui. Prior to going to Singapore, I was involved in national projects and a robotics center at NPU, China, supervised by Prof. WAN Shuai and Prof. MEI Shaohui.
