I am a fourth year Ph.D. student in the Department of Electrical and Computer Engineering at Cornell University. I am a member of the Cornell Computer Systems Lab, advised by Professor Zhiru Zhang. My research interests include hardware-aware algorithmic techniques for high-performance machine learning. My work builds towards using these techniques to construct emerging perception and learning systems on the edge.

I received my bachelor's degree from ShanghaiTech University in 2018.
