About Me
I am a fourth-year Statistics PhD student at the University of Chicago, where I am fortunate to be advised by Professor Haifeng Xu. Prior to joining UChicago, I had an wonderful year at the Saw Swee Hock School of Public Health from 2020 to 2021, working on epidemic modeling under the supervision of Professor Hannah Clapham. I completed my undergraduate studies at the National University of Singapore from 2016 to 2020, with double degrees in Statistics and Economics. My Bachelor’s thesis was guided by Professors Alex Cook and Junjian Yi.
