I lead frontier evals for gemini at Google DeepMind.

I want to build the evals of the future. If that mission excites you, get in touch.

Previously, I was an assistant professor at the University of Cambridge. Before that, I was a researcher in the Visual Geometry Group and a research fellow at Balliol College.

I’m based in King’s Cross, London’s techno-optimist postcode. Let’s build well.

A masterfully drawn cartoon depiction of Samuel hiking cheerfully in the mountains. In the background, three gulls hover in an ecologically implausible formation above snowcapped mountains. Samuel carries a stick and wears a knapsack on his back of the kind that is only used to illustrate the Knapsack Problem. The image is signed skillfully, but illegibly. It's the kind of signature that conveys a profound passion for the digital form.
