Yao-Ching Hsieh

I am a third year PhD student at the University of Washington, advised by Huijia (Rachel) Lin and Stefano Tessaro. I am a member of the cryptography group. I am broadly interested in various aspects of cryptography, and my recent focus lies in lattice-based crypto primitives.

Prior to joining Paul G. Allen School of Computer Science and Engineering at UW, I was a research assistant at IIS, Academia Sinica, Taiwan, where I was advised by Kai-Min Chung. Before that, I received my BS in computer science at National Taiwan University.
