Hi there 👋, I am Fangzhao. I am a PhD student in the Department of Electrical Engineering at Stanford University, advised by Mert Pilanci and Stephen Boyd. Prior to joining Stanford, I obtained my bachelor’s degree from the University of British Columbia, majoring in combined honors computer science and math. My research interest lies broadly in convex optimization and deep learning.
I'm open and happy to chat about research ideas :)
