Source-backed maps of a hard world.

I build source-backed intelligence products about frontier technology and great-power competition. I work in political risk now, and I am moving toward AI safety, governance, and alignment.

The recurring form is the atlas: a public map of a hard domain, with every claim traceable to its source. China's AI stack, semiconductor tooling, rare-earth capability, the maritime grey-zone. Each one is built so a newcomer can learn the domain and a specialist can still find something they had not been tracking. The standard is one line: confident presentation, humble architecture. State the finding clearly. Show the evidence and its limits. Never blur a claim with a guess.

I trained at SAIS, at the intersection of emerging technology, governance, security, and climate. I grew up across Shanghai, Beijing, and Hong Kong, and I live in the DC area now. Away from the work, I follow marine mammals, aviation, geography, and history. They shape how I think about systems, movement, and power.
