Hi! I am a second-year Ph.D. student in Computer Engineering at University of Southern California, starting from Fall 2023. I am fortunate to work with Professor Viktor Prasanna.

I am working on FPGA acceleration of homomorphic encryption and its applications in privacy-preserving machine learning.

Previously, I worked with Professor Li Jiang and Professor Zhezhi He on CNN accelerator. I obtained my bachelor's degrees from University of Electronic Science and Technology of China and University of Glasgow, and master's degree from University of Pennsylvania.
