Christopher Stubbs is an experimental physicist working at the interface between particle physics, cosmology and gravitation. His interests include experimental tests of the foundations of gravitational physics, searches for dark matter, characterizing the dark energy, and observational cosmology.
He was a member of one of the two teams that first discovered the dark energy by using supernovae to map out the history of cosmic expansion. Stubbs is heavily engaged in the construction, commissioning, and upcoming operations of the Vera C. Rubin Observatory, for which he was the inaugural project scientist. He is a member of the JASON group that advises the US government on technical matters that pertain to national security. Stubbs also has a strong interest in generative AI, and serves as the Senior Advisor on this topic for the Dean of the FAS at Harvard.
