John Cobb is Emeritus Professor of Physics and a Senior College Lecturer.

He has a long association with Keble, where he matriculated as an undergraduate in 1968. After finishing his D. Phil in Oxford, he spent several years at CERN in Geneva and the remainder of his research career in the Oxford sub-department of Particle Physics. His research ranged from the electromagnetic phenomena which occur when relativistic particles pass through matter to a search for proton decay. He introduced the first long-baseline neutrino oscillation experiment to the Oxford physics department. Most recently he worked on a demonstration of the ionisation cooling of muon beams, necessary for the development of neutrino ‘factories’ for the precision study of neutrino oscillations. He has taught physics at Keble for over thirty years with the ambition that students not only learn physics but also learn to think and communicate clearly.
