'''Pran Nath''' is a [[theoretical physicist]] working at [[Northeastern University]], with research focus in elementary particle physics. He holds a Matthews Distinguished University Professor chair.

==Research==
His main area of research is in the fields of [[supergravity]] and [[particle physics]] beyond the standard model. He is one of the originators of the first supergravity theory in 1975.<ref>{{cite journal | last=Nath | first=P. | last2=Arnowitt | first2=R. | title=Generalized super-gauge symmetry as a new framework for unified gauge theories | journal=Physics Letters B | publisher=Elsevier BV | volume=56 | issue=2 | year=1975 | issn=0370-2693 | doi=10.1016/0370-2693(75)90297-x | pages=177–180}}</ref><ref>{{cite journal | last=Arnowitt | first=R. | last2=Nath | first2=P. | last3=Zumino | first3=B. | title=Superfield densities and action principle in curved superspace | journal=Physics Letters B | publisher=Elsevier BV | volume=56 | issue=1 | year=1975 | issn=0370-2693 | doi=10.1016/0370-2693(75)90504-3 | pages=81–84}}</ref> In 1982 in collaboration with [[Richard Arnowitt]] and [[Ali Chamseddine|Ali Hani Chamseddine]], he developed the field of Applied Supergravity<ref>P.

==Life and career==
He was born in [[Punjab Province (British India)|West Punjab]], [[British India]] in 1939, and is of [[Kashmiri people|Kashmiri]] descent. He received his [[bachelor's degree]] in Science at the [[University of Delhi]] in 1958, and his [[Doctor of Philosophy|Ph.D.]] degree from [[Stanford University]] in 1964. He taught at the [[University of California, Riverside]] 1964-65, and was Andrew Mellon Fellow at the [[University of Pittsburgh]] from 1965-66. Since 1966 he has been at [[Northeastern University]]. He has held visiting positions at [[TIFR]], [[Mumbai]] under the [[United Nations Development Program]], at the [[University of California, Santa Barbara]], at [[Bonn]], [[CERN]], [[Heidelberg]] and [[Munich]]. He was co-chair of the conference "Gauge Theories and Modern Field Theory", in 1975, and founding chair in 1990 of the annual PASCOS symposium (Particle physics, String theory and Cosmology), and also the founding chair in 1993 of the annual conference [[SUSY]]. In 2004 PASCOS symposium held a special Pran Nath Festschrift honouring his "pioneering contributions over four decades in the fields of high energy theory, supersymmetry, supergravity, and unification".<ref>G.
