Zhifei Yang

I am a systems engineer and researcher. I am interested in the art of computer systems design and implementation. Recently, my focus is on building datacenter software infrastructure for emerging cloud and AI use cases.

I was fortunate enough to have research experiences from EPFL and the University of Chicago. Before that, I finished my master's degree from ETH Zürich and bachelor's degree from Harbin Institute of Technology.
