My research currently focuses on mitigating catastrophic risks from advanced AI, looking particularly at increasing U.S. government capacity, improving frontier lab security, and reducing AIxNuke risks. Previously, as a more traditional defense policy researcher, I prioritized work that aimed to reduce the risks of war and encourage more effective U.S. and allied defense and foreign policy decisions. My research methodology is reading a lot, writing a little, and asking smart people (and now LLMs) to review and improve my work.
