I'm a full-time research assistant currently hosted by Prof Vincent Tan at National University of Singapore. I mostly work on data privacy. Prior to this, I graduated with Bachelor of Computing (Computer Science) with Honours (Highest Distinction) and Bachelor of Science with Honours (Highest Distinction) in Mathematics from National University of Singapore in June 2023, where I was very fortunate to be advised by Prof Xiaokui Xiao and Prof Vincent Tan.
