- Safety and tamper resistance for open-weight AI models.
- Predicting and preventing major AI incidents.
- Navigating technical ambiguities, challenges, and loopholes in frontier AI laws.
- Tenacity -- e.g., A demonstrated habit of applying self-taught skills to make projects succeed, even when one was not put in a position to make them succeed. For example, I think it is a very green flag if an undergraduate electively writes a paper by themselves over the course of a summer without that paper being connected to a class internship or job.
