Buck Shlegeris — Notable For: AI safety research; Redwood Research leadership

NoteThe source confirms both components of the claim: (1) AI safety research is confirmed by his explicit statement about working on 'existential risk reduction' and his blog post on 'My personal cruxes for working on AI safety', and (2) Redwood Research leadership is confirmed by his statement that he is 'currently the CTO of Redwood Research'. The source does not provide a specific date, but the claim's 'as of 2026-03' date cannot be contradicted by a source that uses present tense ('I'm currently'). The source is Buck Shlegeris's personal website, making it the appropriate source for verifying his current roles and research focus.
