==Early life and education==
Raychaudhuri was born in [[Calcutta, India]] and did his schooling at the [[South Point School (India)]].<ref>{{cite web |url=http://www.aspexs.com/aspexs/Exceptional.aspx?PageIndex=2...5 |title=South Point Ex Students' Association :: Exceptional |website=www.aspexs.com |url-status=dead |archive-url=https://web.archive.org/web/20160303222905/http://www.aspexs.com/aspexs/Exceptional.aspx?PageIndex=2...5 |archive-date=2016-03-03}}</ref> He later attended [[Presidency College, Kolkata|Presidency College, Calcutta]] from where he obtained his [[Bachelor of Science|BSc]] degree in [[Physics]] in 1970 and then went on to complete his [[Master of Science|MSc]] degree at [[Delhi University]] in 1973. Under the supervision of [[Oscar Greenberg|Oscar W. Greenberg]], Raychaudhuri obtained his [[Doctor of Philosophy|PhD]] degree in [[Particle physics|Particle Physics]] from the [[University of Maryland, College Park]] in 1977.{{Citation needed|date=June 2017}}

==Research and career==

After postdoctoral work at the [[University of Oxford]] and the [[Tata Institute of Fundamental Research]], [[Mumbai]] he joined the [[Rajabazar Science College]] campus of [[University of Calcutta]] in 1980 as a lecturer in [[physics]], where he became Reader and then the Sir Tarak Nath Palit Professor. During his tenure at the [[University of Calcutta]], he was a Scientific Associate (1983–84) at [[CERN]], Senior Indo-US [[Fulbright Fellow]] (1988–89) at the [[Lawrence Berkeley Laboratory]] and Senior [[Marie Curie]] Fellow (1994) at the [[University of Cambridge]]. He was also a Visiting Professor (1998) at the [[Oklahoma State University]]. He was the Director of the [[Harish-Chandra Research Institute]], [[Allahabad]] from 2005 to 2011 after which he rejoined the [[University of Calcutta]] as faculty.<ref>{{Cite web|url=http://inspirehep.net/author/profile/A.Raychaudhuri.1|title = Inspire}}</ref>

Raychaudhuri has worked in diverse areas within particle physics encompassing [[quantum chromodynamics]], [[grand unified theories]], classical solutions, left-right symmetric models, [[FCNC]], [[supersymmetry]], [[neutrino]] physics, [[extra dimensions]], etc.{{Citation needed|date=June 2017}} He made contributions in [[CPT symmetry|CP-violation]] in [[Supersymmetry|supersymmetric]] models, the possibility of parity restoration at relatively low energies, [[neutrino]] masses and mixing in [[Supersymmetry|supersymmetric]] and other models, long baseline [[neutrino]] experiments, besides making a brief but important foray in the foundations of [[quantum mechanics]].<ref name="test1" />

==Awards and achievements==
He was the recipient of the [[Indian National Science Academy|INSA]] Young Scientist Award in 1982, the [[Shanti Swarup Bhatnagar Prize for Science and Technology]], the highest science award in [[India]], in the physical sciences category in 1997, the J.C. Bose fellowship, the National Merit Certificate and Prize and the National Science Talent Search Scholarship in 1967.<ref>{{Cite web|url=http://www.physics-caluniv.in/research-theoretical-high-energy-and-nuclear-physics.html|title=Department of Physics - Calcutta University|access-date=11 February 2013|archive-date=30 August 2021|archive-url=https://web.archive.org/web/20210830141917/https://physics-caluniv.in/research-theoretical-high-energy-and-nuclear-physics.html|url-status=dead}}</ref> He is a Fellow of the [[Indian National Science Academy]], [[National Academy of Sciences, India|National Academy of Sciences]], [[Allahabad]] and the [[Indian Academy of Sciences]], [[Bangalore]]. He was also a two-term senior associate of the [[Abdus Salam International Centre for Theoretical Physics]] (ICTP), [[Trieste]], [[Italy]]. In 2005, Raychaudhuri was conferred the honour of International Alumnus of the Year by the [[University of Maryland, College Park|University of Maryland]] Alumni Association. He is a recipient of D.Sc. (honoris causa) from the University of Gour Banga and the [[University of North Bengal]].
