'''Echur Varadadesikan Sampathkumaran''' (born 6 December 1954) is an Indian condensed matter physicist and a Distinguished Professor at the [[Tata Institute of Fundamental Research]]. Known for his research on the thermal and transport behaviour of magnetic systems, Sampathkumaran is an elected fellow of all the three major Indian science academies viz. [[Indian Academy of Sciences]], [[Indian National Science Academy]] and [[National Academy of Sciences, India]] as well as [[The World Academy of Sciences]]. The [[Council of Scientific and Industrial Research]], the apex agency of the Government of India for scientific research, awarded him the [[Shanti Swarup Bhatnagar Prize for Science and Technology]], one of the highest Indian science awards, for his contributions to physical sciences in 1999.<ref name="View Bhatnagar Awardees">{{Cite web |url=http://ssbprize.gov.in/Content/AwardeeList.aspx |title=View Bhatnagar Awardees |date=2017-11-11 |publisher=Shanti Swarup Bhatnagar Prize |access-date=2017-11-11}}</ref>{{Refn|group=note|Long link - please select award year to see details}}

E. V. Sampathkumaran, born on 6 December 1954 in the south Indian state of [[Tamil Nadu]], earned his BSc degree from the [[University of Madras]] before obtaining a master's degree from [[Annamalai University]].<ref name="Indian fellow">{{Cite web |url=http://insaindia.res.in/detail/P02-1322 |title=Indian fellow |date=2017-10-17 |publisher=Indian National Science Academy |access-date=2017-10-17}}</ref> Subsequently, he joined [[Tata Institute of Fundamental Research]] as a member of faculty in 1976.<ref name="Biographical Information">{{Cite web |url=http://www.tifr.res.in/~sampath/cv_evs_oct2016.pdf |title=Biographical Information |date=2017-10-18 |website=Tata Institute of Fundamental Research |access-date=2017-10-18}}</ref> During this period, he enrolled at the [[University of Mumbai]] for doctoral studies on ''valence fluctuations in rare-earth compounds'' and secured a PhD in 1982, guided by [[Ramanuja Vijayaraghavan]], a [[Shanti Swarup Bhatnagar Prize for Science and Technology|Shanti Swarup Bhatnagar laureate]]. He did his post-doctoral work on ''valence fluctuations'' as an [[Alexander von Humboldt Fellow]] at the [[Free University of Berlin]], under the guidance of G. Kaindl, during 1983–84 and returned to TIFR to resume his career there. Barring two sabbaticals, the first as an Indo-Waseda Exchange Visitor for two months in 1988 to Japan and the other, a two-month stint at [[Paderborn University]] in 1996, his entire career was spent at TIFR, holding various positions. During 2008–10, he chaired the Department of Condensed Matter Physics and Materials Science after which he served as the dean of the Natural Sciences faculty from 2010 to 2013. After his superannuation in 2014, he continues his association with the institute as a Distinguished Professor.<ref name="Distinguished Professor">{{Cite web |url=http://www.tifr.res.in/~sampath/ |title=Distinguished Professor |date=2017-10-18 |website=Tata Institute of Fundamental Research |access-date=2017-10-18}}</ref> He also had a brief stint as the director of the institute during April–July 2015<ref name="TIFR council to name new director soon">{{Cite web |url=https://timesofindia.indiatimes.com/City/Mumbai/TIFR-council-to-name-new-director-soon/articleshow/46800206.cms |title=TIFR council to name new director soon |date=2017-10-18 |website=Times of India |access-date=2017-10-18}}</ref> and served as an Honorary Professor at [[Jawaharlal Nehru Centre for Advanced Scientific Research]] from 2001 to 2015.<ref name="Biographical Information" />
