Personnel: Paul Christiano at OpenAI (Researcher)

Note: The source confirms Paul Christiano worked at OpenAI in a leadership role on the language model alignment team, and that this was a previous position (not current). However, the source does not provide specific start and end dates (2017-01 and 2021-10). The source confirms the person, organization, and general role, but the precise dates are unverifiable from this text. The role description as 'Researcher' is also somewhat imprecise—the source indicates he 'ran' the alignment team, suggesting a leadership position rather than a generic researcher role, though this is not a direct contradiction.
