Tarun Souradeep

Prof. Tarun Souradeep

Professor Tarun Souradeep assumed charge as Director, Raman Research Institute on 20th January 2022. Before coming to RRI, he was a professor and the Chair of the Physics Department at IISER, Pune. Prof. Souradeep’s area of expertise is Cosmology and Gravitational Wave Physics and Astronomy, areas in which he has made important contributions and succeeded in creating a strong, sustained Indian effort addressing issues at par with international research. The impact of the Indian team led by him is widely recognized, both in the field of cosmology with frontline Cosmic Microwave Background experiments (CMB), and the emergent field of gravitational wave (GW) astronomy.

He is the spokesperson (Science) for LIGO-India and Member Secretary of LIGO - India Scientific Management Board. Together with Prof Bala Iyer (then at RRI), he was one of lead proposers of the national mega-science LIGO-India project way back in 2011. He is a recipient of various awards including DST Swarnajayanti Fellowship, Gruber Cosmology Prize 2016 and 2018 and the Special breakthrough Prize for 2016. He is a fellow of the National Academy of Sciences and the Indian Academy of Sciences. His election to the fellowship of the International Society on General Relativity and Gravitation is a testament to his standing among his international peers.
