Personnel: Ben Cottier at Epoch AI (Staff Researcher)

NoteThe source confirms three of four key fields: person (Ben Cottier), org (Epoch AI), and role (Staff Researcher). However, the startDate of 2022 is not mentioned in the source text. The source provides no information about when Ben Cottier began his role at Epoch AI, making the start date claim unverifiable from this source. The role title matches exactly ('Staff Researcher'), and the organization is confirmed (though referred to as 'Epoch' in the source, which is consistent with 'Epoch AI').
