I am a first year Computer Science PhD student at Stanford University. I am fortunate to be advised by Prof. Dan Boneh. I am currently interested in cryptography, especially on theories for building privacy preserving applications.

Before joining Stanford, I had worked as a research engineer at CryptoLab for 3 years. I actively engaged in academic research and software development on fully homomorphic encryption (FHE).
