About Me

I am currently a third-year PhD candidate of the CSE department in The Hong Kong University of Science and Technology (HKUST), supervised by Prof. Raymond Chi-Wing WONG. I obtained my BEng degree in Computer Engineering and my MPhil degree in Computer Science also from HKUST in 2017 and 2019, respectively.
