[[File:Holkar college.jpg|thumb|235px|left|Holkar Science College in 1964]]
J. G. Negi, born on 1 August 1936 in the tribal village of Khidhgaon of [[Khandwa district East Nimar]] in the Indian state of [[Madhya pradesh]] to Ganpatrao and Laxmi Devi, completed his graduate studies in science at Victoria College (present-day MLB Government College of Excellence) in 1956 before obtaining a master's degree from Dan Singh Bisht Government College, [[Nainital]] in 1958.<ref name="Dr. Janardan Ganpatrao Negi on IGU">{{Cite web |url=http://j-igu.in/igu%2020-2%20(web)/16-news%20and%20views.pdf |title=Dr. Janardan Ganpatrao Negi on IGU |date=2016 |publisher=Indian Geophysical Union}}</ref> His academic career started at [[Holkar Science College]] of [[Jiwaji University]] as a lecturer where he worked from 1958 to 1959 during which time he enrolled at the [[Indian Institute of Technology, Kharagpur]] for his doctoral studies and secured a PhD in 1962. He continued at IIT Kharagpur for two more years as a research scholar and joined [[National Geophysical Research Institute]], Hyderabad in 1964 as a senior scientific officer. He spent the rest of his official career at NGRI, serving in such various positions as assistant director (1971–79), senior assistant director (1979–82), deputy director (1982–83), senior deputy director (1983–90) and director grade scientist to superannuate from service in 1996 as the director. Post retirement, he serves as an emeritus scientist of the institute.<ref name="NASI fellows" />

Negi's theoretical studies have been focusing on the areas of geoelectromagnetics and geomagnetism of geophysics and his researches have assisted in the wider understanding of gravity, heat flow and electromagnetic fields of Earth's surface.<ref name="Handbook of Shanti Swarup Bhatnagar Prize Winners">{{cite web | url=http://www.csirhrdg.res.in/ssb.pdf | title=Handbook of Shanti Swarup Bhatnagar Prize Winners | publisher=Council of Scientific and Industrial Research | date=1999 | access-date=15 December 2016 | archive-url=https://web.archive.org/web/20160304043957/http://www.csirhrdg.res.in/ssb.pdf | archive-date=4 March 2016 | url-status=dead }}</ref> His studies have been detailed in a book, ''Anisotropy in Geoelectromagnetism'',<ref name="NegiSaraf1989">{{cite book|author1=J.
