Biography
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.[6] 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.[4]

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.[7] His studies have been detailed in a book, Anisotropy in Geoelectromagnetism,[8] as chapters in books by others,[9] and as several peer reviewed articles[note 1] and his work has been cited by many authors.[10][11][12] He headed the Madhya Pradesh Council of Science and Technology as its director general and served as the scientific advisor to the Government of Madhya Pradesh for two terms during 1992–94 and 2005–06.[4] When the Institute of Seismological Research, Gandhinagar was established in 2003, he served as the founder director general of the institution till 2005. He is a former UNESCO lecturer and a visiting faculty at many universities including Cooperative Institute for Research in Environmental Sciences, Federal University of Bahia and Federal University of Pará.[6]

Negi is married to Asha Billore and the couple has two sons, Atul and Madhav.

Awards and honors

Negi received the Krishnan Medal of the Indian Geophysical Union in 1974.[13] The Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards, in 1980.[14] A life fellow of the Royal Astronomical Society, he was elected as a fellow by the National Academy of Sciences, India in 1984,[4] the same year as he received the National Lectureship of the University Grants Commission of India.[6] He is also a recipient of the Holkar Science College Centenary Award, Vigyan Ratna and the 1991 Lifetime Achievement Award of the Association of Exploration Geophysicists. The award orations delivered by him include the Dr. H. N. Siddique Memorial Lecture of the Indian Geophysical Union in 2003.[15]
