Professor Jonathan Ellis CBE FRS
Jonathan Ellis has made numerous contributions to the theory of elementary particles and especially unified gauge theories. Particularly notable were the first proposal of three jet structure (subsequently seen experimentally) as a gluon signal, and the first precise application of the renormalization group to grand unified theories, with the first precise estimate of sin2 θ W. Works on the theory of CP violation, on the phenomenology of the Higgs boson, and on the implications of grand unified theories for the generation of baryon number in the early Universe, have also attracted much attention. His gift for communication (his summer school lectures and reviews are models of their kind), and his special concern with the experimental implications of topical theories, make him a key figure in the discussion of new high-energy physics projects.
