I am a Clay Research Fellow and Stanford Science Fellow in the Department of Mathematics at Stanford University. I previously obtained my PhD from Stanford University, where I was very fortunate to be advised by Professor Jacob Fox. I got my BS in Mathematics and MS in Statistics with Honors and Distinction from Stanford University, and a Master of Advanced Study in Mathematics with Distinction from the University of Cambridge.
