Personnel: Beth Barnes at METR (Founder & CEO)

NoteThe source text is from METR's website and confirms METR exists as an organization conducting AI research and evaluations. However, the provided excerpt contains no information about Beth Barnes, her role as Founder & CEO, or the start date of 2023-01. The source discusses METR's research, evaluation reports, press coverage, and recent work, but does not include personnel/leadership information. To verify the claim about Beth Barnes' role and start date, a source that explicitly discusses METR's leadership or founding would be required. The absence of this information in the provided text makes the claim unverifiable from this source alone.
