About

Short Bio

I am currently a Ph.D. student advised by Prof. Jing Gao in the Elmore Family School of Electrical and Computer Engineering at Purdue University. Before joining Purdue in 2022, I worked with Prof. Song Guo at the Pervasive Edge Intelligence Laboratory (PEILab). I obtained my B.Sc. degree in Computing (major) and Applied Mathematics (minor) from The Hong Kong Polytechnic University in 2020. During my Ph.D. study, I have been working as a research intern at Alibaba Group. I have served as a reviewer for a number of prestigious conferences, such as ICML, NeurIPS, ICLR, and KDD. I was a recipient of Best Student Paper from ACM BSCI'19.
