Spenta R. Wadia (born 1 August 1950) is an Indian theoretical physicist with research interests in elementary particle physics, quantum field theory and statistical physics, string theory and quantum gravity. His other scientific interests are in complex systems including cross-disciplinary biology. He is a recipient of the 2004 TWAS Prize in Physics; the 1995 Physics Prize of the International Centre for Theoretical Physics (ICTP); and the J. C. Bose Fellowship of the Govt of India. He is an elected member of TWAS, and a Fellow of all the Science Academies of India. Career He is an alumnus of St Mary’s High School Mumbai, St Xavier’s College Mumbai and IIT-Kanpur. He graduated from the City University of New York in 1978 (mentor Bunji Sakita) and his postdoctoral work at the University of Chicago (mentors Yoichiro Nambu and Leo Kadanoff). He joined the faculty of the Tata Institute of Fundamental Research (TIFR) in Mumbai in 1982 and worked there till 2015. He was the Chair of the Dept of Theoretical Physics 2007-2009, Distinguished Professor 2008-2015 and Founder Director of the International Centre for Theoretical Sciences (ICTS) of TIFR in Bangalore 2007-2015. Presently he is the Infosys Homi Bhabha Chair Professor at ICTS. He was a visiting member of the Institute for Advanced Study at Princeton, USA during 1990-1992; Centre European Recherché Nuclear (CERN) in Geneva, during 1996-1997 and 2003-2004; KITP Simons Distinguished Visiting Scholar 2018. Contribution to Indian and International Science He conceived and executed (with the contribution of many colleagues) the International Centre for Theoretical Sciences of TIFR. This institution through its programs, research and outreach activities is having an impact on Indian science and education. He also contributed significantly to the building of the Department of Theoretical Physics of TIFR, especially the string theory group. He is one of the founding members of i) the Asian Winter School on “Strings, Particles and Cosmology”, a meeting that is held sequentially every year since 2007 in Korea, Japan, China, and India; ii) the “Crete Regional Meeting in String theory” held biennially since 2001 where physicists from Iran, Israel, India and other countries of the Middle East meet. He was one of the main organizers of Strings 2001 in Mumbai and Strings 2015 in Bangalore. In his role as a member of the "Committee for International Scientific Affairs" of the American Physical Society, he has enabled several joint events with the Indian Physics
