'''Tiruppattur Venkatachalamurti Ramakrishnan''' {{post-nominals|size=100%|country=GBR|FRS}} (born 14 August 1941) is an Indian [[theoretical physicist]] known for his contributions in [[condensed matter physics]]. He is at present [[Department of Atomic Energy (India)|DAE]] [[Homi J. Bhabha|Homi Bhabha]] Professor of Physics at [[Benaras Hindu University]] and also the chancellor of [[Tripura University]].

==Biography==
Tiruppattur Venkatachalamurti Ramakrishnan was born on 14 August 1941 in [[Madras]], [[Tamil Nadu]]. He completed his [[Bachelor of Science|B.Sc (Hons.)]] and [[Master of Science|M.Sc]] in Physics from [[Banaras Hindu University]] in 1959 and 1961. He then worked as a [[Council of Scientific and Industrial Research|CSIR]] [[research fellow]] at [[Banaras Hindu University]] from 1961 to 1962. He later completed his [[Ph.D.]] from [[Columbia University]] in 1966.<ref name='TVRcv'>{{cite web | url = http://www.physics.iisc.ernet.in/~tvrama/cv1.htm | title = Curriculum Vitae of T. V.

==Career==
Spenta Wadia did his bachelors from [[St. Xavier's College, Bombay]] and masters from [[Indian Institute of Technology, Kanpur]]. He obtained his Ph.D. from City College of [[City University of New York]] in 1978. He then worked at [[University of Chicago]] from 1978-82 first as a research fellow and then as a staff scientist. He finally moved to the [[Tata Institute of Fundamental Research]] in 1982 where he remains to this day. He also served on the Physical Sciences jury for the [[Infosys Prize]] from 2015 to 2017.

==Research==
Spenta Wadia’s main research interests are in quantum field theory, statistical mechanics, string theory and quantum gravity. There is considerable overlap of these areas in light of the gauge-gravity duality of string theory. His other scientific interests are in complex systems including cross-disciplinary biology.
