About me

I am currently a fourth-year (2018–now) PhD student in Computer Science Department at The University of Hong Kong. I am under the supervision of Prof. Heming Cui link.

I am broadly interested in distributed systems, security and AI. I have been focusing on building practical trusted hardware-based (e.g., SGX) systems to secure decentralized computing (e.g., Internet-scale private messaging, blockchain) and AI training/inference.
