Zhifei Yang

Research Engineer @ EPFL, Switzerland

I am a research engineer at the Laboratory for Computation Security of EPFL, led by Prof. Alessandro Chiesa. Currently, I work on applied cryptography and implementations of zero-knowledge proofs.

I am generally interested in computer systems, security and privacy. I have various systems research experiences from EPFL, the Univeristy of Chicago, ETH Zürich and MSRA. I hold a master's degree from ETH Zürich and a bachelor's degree from Harbin Institute of Technology.
