He graduated from Oxford University (Master of Arts 1971, Doctor of Philosophy 1974).
He has held positions at Imperial College, Massachusetts Institute of Technology, Caltech, European Organization of Nuclear Research and the University of Rome. He went to Fermilab in 1984. He was Head of the Theoretical Physics Department at Fermilab from 1993 to 2004.
Ellis" work is of importance to the study of elementary particles at colliders, such as the Fermilab Tevatron, and the European Organization of Nuclear Research Large Hadron Collider.
Ellis has contributed in a substantial way to the interpretation of experiments performed at high energy. Together with Douglas Ross and Tony Terrano he performed the first calculation of jet structure in e+eannihilation which allowed precise determination of the strong coupling.
In addition, with Guido Altarelli and Guido Martinelli he performed a calculation of lepton pair production which allow reconciliation of observed rates with theoretical calculations. He has also co-authored a number of widely read papers on the theory of heavy quark production.
He is also co-author for the parton-level Monte Carlo program MCFM. Honours and J. R.
In 2015 he moved to the University of Durham in the United Kingdom, where he is a professor of Physics and Director of the Institute for Particle Physics Phenomenology.
