Sijun Tan (谭嗣俊)

I am a CS PhD student at UC Berkeley, advised by Raluca Popa. I am affiliated to Berkeley’s Sky Computing Lab.

Previously, I graduated from University of Virginia with a Bachelor’s degree in Computer Science and Mathematics, where I was advised by David Wu and Yuan Tian. I also worked with Professors Haifeng Xu and Xiaohui Bei.

My research interest lies in cryptography and computer security. In particular, I study cryptographic primitives such as Secure Multi-party Computation (MPC) and Zero-knowledge Proof (ZKP), and leverage them to build decentralized systems. If you are interested in research collaboration, please shoot me an email.
