My research focuses on building reliable and trustworthy systems, spanning operating systems, blockchain infrastructure, and AI agent systems. I am currently exploring how to rebuild system infrastructure to make AI agents more efficient and secure, and advancing cryptocurrency anti-money-laundering (AML) and on-chain criminal investigation to combat crypto-enabled financial crime. I co-founded BlockSec, a company delivering blockchain security and compliance solutions.
