About

Hi! I’m Richard and I am a Quantitative Technologist at Radix Trading in Chicago.

Before that, I completed my BS in Electrical Engineering and Computer Science at UC Berkeley where I taught CS 70 for 7 semesters and lead a research group exploring federated learning, advised by James Demmel.
