About

I am a second-year PhD student in Mathematics at Harvard University, broadly interested in arithmetic geometry, arithmetic statistics, and number theory. My advisor is Professor Bjorn Poonen. Here is my CV.

I graduated from National University of Singapore with a Bachelor's degree in Science (with Honours), majoring in Mathematics. My undergraduate advisor was Professor Wee Teck Gan.
