Submission declined on 18 July 2024 by Twinkle1990 (talk). This submission's references do not show that the subject qualifies for a Wikipedia article—that is, they do not show significant coverage (not just passing mentions) about the subject in published, reliable, secondary sources that are independent of the subject (see the guidelines on the notability of people). Before any resubmission, additional references meeting these criteria should be added (see technical help and learn about mistakes to avoid when addressing this issue). If no additional references exist, the subject is not suitable for Wikipedia. This submission is not adequately supported by reliable sources. Reliable sources are required so that information can be verified. If you need help with referencing, please see Referencing for beginners and Citing sources.

Life, education and career
[edit]Supriya Kumar Kar was an Indian theoretical physicist (5 August 1967– 5 May 2024) born in Adra, West Bengal, India. He specialized in theoretical high energy physics, string theory, D-branes, general relativity, cosmology, quantum gravity and noncommutative geometry. Supriya Kar obtained his B.Sc. degree from the Utkal University (FM College Baleshwar) in 1987 and his M.Sc. (Physics) degree from Utkal University (Vani Vihar) in 1990. He obtained his PhD degree from the Institute of Physics, Bhubaneswar in 1995. Soon after his PhD, he joined Harish Chandra Research Institute, Allahabad (1995-1996). He then received an award of the prestigious JSPS Postdoctoral Fellowship in theoretical High Energy Physics at the University of Tokyo (1996-1998). Subsequently he got an award of the Postdoctoral Research Associateship at the Chalmers University of Technology, Goteborg in quantum gravity and string theory group. He held the position of an Assistant Professor of Physics at the Indian Institute of Technology Kanpur during March 2001-December 2002. Eventually, he got appointed to a permanent faculty position as an Assistant Professor of Physics at the Department of Physics and Astrophysics, University of Delhi (2002-2007), where he again got appointed on an open position of Reader in Physics (2007-2010) and subsequently got promoted to a position of an Associate Professor of Physics (2010-2013). Eventually he got promoted to a position of (Full) Professor of Physics in 2013,[32] a position which he held until he breathed his last on May 5, 2024, when his brilliant academic career came to an abrupt end at a young age of fifty six [33]
Scientific Research
[edit]Supriya Kumar Kar's research was focussed on theoretical high energy physics, string theory, superstring theory, D-branes, general relativity, cosmology, quantum gravity and non-commutative geometry, emergent gravity, quintessence and blackhole geometries and he published very widely in this field.[34],[35]During his short illustrious career at the University of Delhi he was able to produce five PhD's. He authored the Book (by invitation) on Noncommutative geometry: A Perspective on String and Field Theories.[36] World Scientific Singapore (2021). He was an Editor of a Special Issue on Black Holes and Cosmology, Journal of Astrophysics and Aerospace Technology (2017).[37] He was one of the co-editors of an Edited Volume of Nuclear Physics B Proceedings Supplements on the International Conference on Light-Cone Physics: Hadronic and Particle Physics, Nuclear Physics B Proceedings Supplement 251-252 (2014) along with others (2014).[38]
Kar has written over 70 scientific articles[39],[40] which have received a large number of citations (over 500).
Graduate Students
[edit]During his academic career at the University of Delhi, Supriya Kar was able to produce five graduate students: Abhishek Kumar Singh (on geometric aspects of D-brane in string theory (2008-2014)), Sunita (on D-brane-world and string theory (2009-2014)), K. Priyabrata Pandey (on blackholes, branes and strings (2009-2014)), Deobrat Singh (on (Anti) de Sitter blackholes in string theory (2011-2021)), Nitish (on some aspects of non-perturbative quantum gravity in a two form gauge theory (2016-2021)), Rohit K. Gupta (on boundry quantum gravity (submitted PhD thesis to the University of Delhi on 6 November 2023)), his last PhD student Jitesh Kumar is yet to submit his PhD thesis. He was also an advisor of a post-doctoral fellow Rohit Kumar (PhD BHU Varanasi) at the Delhi University for a period of five years.
