Currently Thinking About

AI governance, what it means to do research that matters.

About

I'm a visiting student at UC Berkeley, working at the intersection of software engineering and the social implications of AI. I build things to understand them.

Previously at SUSTech (Shenzhen), studying computer science and mathematics. This site is where I keep notes on what I'm building and thinking about.
