I am a researcher, trader, and entrepreneur, specializing in quantitative trading and machine learning. I am a graduate student in the EECS department at MIT and a member of CSAIL and the Machine Learning group.

I am fortunate to be advised by Stefanie Jegelka. Previously, I was an undergraduate at UBC, where I was fortunate to be advised by Nick Harvey. I also seasonally visit Ken-ichi Kawarabayashi at NII in Tokyo.
