Physicist Christopher Stubbs Joins Anthropic Trust

Anthropic announced this week that experimental physicist Christopher Stubbs has joined its Long-Term Benefit Trust, bringing decades of expertise in observational cosmology and precision measurement, along with experience advising the US government on national security and arms control. Stubbs said he uses AI tools in his research every day and wants to help ensure AI is developed and deployed for humanity’s long-term benefit. He is the Trust’s first physicist.

Stubbs is Harvard’s Samuel C. Moncher Professor of Physics and Astronomy and served as its Dean of Science from 2018 to 2024. In 1998, as part of the High-Z Supernova Search Team, he helped discover the universe’s accelerating expansion; the team later received the Breakthrough Prize in Fundamental Physics. He was the inaugural project scientist for what is now the Vera C. Rubin Observatory, which began a 10-year survey of the southern sky in June. One aim of the survey is to study the expansion he helped discover.

Stubbs has written about keeping AI-assisted research reproducible when models give different answers to the same question. He is also a member of JASON, an independent group that has advised the US government on defense and technology since 1960. Anthropic co-founder and president Daniela Amodei said Stubbs’s intellectual honesty, rigor and commitment to evidence are values the company wants to shape AI’s future.

Anthropic says the Trust helps balance the company’s commercial growth with its public benefit purpose. It can appoint a majority of Anthropic’s board, and its trustees advise the board and leadership on critical decisions, particularly those involving AI risks and societal impacts. This week, Anthropic published its first Public Benefit Report, an account of its work toward its charter and areas where it is falling short. Trustees helped define the five charter pillars used to assess the company, and the report concludes with their assessment of progress. Subject to stockholder approval, Anthropic has also committed to setting aside some company shares for a new Anthropic Public Benefit Fund, whose stake would increase as the company grows.

Trust chair Neil Buddy Shah said Stubbs has led complex collaborative scientific work across academia, government and national laboratories. Stubbs joins Shah, national security expert Richard Fontaine, and former Federal Reserve Chair Ben Bernanke. Anthropic says trustees are independent of its management and investors.
