Prof. Jogesh Pati  has made lifelong contributions to theoretical elementary particle physics.  He is best known for his pioneering contributions towards the notion of a unification of fundamental particles - quarks and leptons - and of their three gauge forces: weak, electromagnetic and strong.  His formulation, carried out in collaboration with Abdus Salam, of the original gauge theory of quark-lepton unification, and their resulting insight that such a unification would lead to violations of baryon and lepton numbers, resulting in proton decay, provide the corner stones of modern particle physics today.  The suggestions by Pati and Salam of the symmetry SU(4) - color, left-right symmetry, and of the associated existence of the right - handed neutrinos now provide some of the crucial ingredients for understanding the observed masses of the neutrinos and their oscillations, as well as of the origin of an excess of matter over anti-matter in the early universe.

Some of his major honors and awards include: (1) The Washington Academy of Sciences Award in Physical Sciences (1973); (2) Distinguished Scientist of the Year Award by the American Chapter of the Indian Physics Association (1991); (3) Distinguished Homi J. Bhabha Professorship, awarded by the Dept. of Atomic Energy, Govt. of India (1999 - ); (4) The Distinguised Lifetime Achievement Award by the American Chapter of the Indian Physics Associate (2011).  In particular, for his "Pioneering Contributions Towards a Quest for Unification", he received the prestigious International Dirac Medal for the year 2000 (with Howard Geogi and Helen Quinn)
