Biography:Kellogg Stelle
Kellogg S. "Kelly" Stelle (11 March 1948–23 October 2025).[1] was an American-British theoretical physicist and professor of physics at Imperial College London. His work was focused on the theory of gravitation, in particular quantum gravity, and braneworld cosmology.[2][3]
He developed the theory of quadratic gravity in 1977. The theory had difficulty being accepted as a viable theory because it postulates the existence of a massive ghost particle.[4] He later turned his interest to supergravity.[4]
A two-day scientific conference, "Kellyfest", to celebrate his 60th birthday was held by the Theoretical Physics Group at Imperial College in 2008.[5]
He was a Fellow of the Institute of Physics and of the American Physical Society.[6] He was a winner of a Humboldt Research Award in 2006, and of the John William Strutt, Lord Rayleigh Medal and Prize in 2020.
He died in 2025.[7]
