Prof G Srinivasan

Prof. G Srinivasan (9th April 1942), a specialist in Condensed matter Physics and Astrophysics had distinguished career as Scientist and a teacher at the Raman Research Institute.

Early Years and Education

Prof. Srinivasan was born in Madurai District of Tamilnadu to V Ganesan and Meenakshi. He graduated from Nagpur University in 1962 with BSc degree and acquired MSc in 1964 from University of Madras. He acquired Doctorate degree in 1970 from University of Chicago, USA.


Prof. Srinivasan began his career as Instructor at American college, Madurai. He joined University of Chicago, USA as Teaching Assistant during 1965-67. From 1967-70 he worked as Research Assistant at James Frank Institute, University of Chicago, USA. He joined IBM Research Laboratory, Switzerland as IBM Fellow during 1971-72; Chalmers University of Technology, Sweden as Research associate from 1972-73; Cavendish Laboratory, University of Cambridge, UK as Member of the Research Staff from 1973-76. He joined Raman Research Institute, Bangalore as Scientist in 1976. He became Associate Professor in 1981 and Professor from 1985-2004. He retired from RRI in 2004. He was Visiting professor at ISRO from 2005-06.

Scientific Work

Prof. Srinivasan was the first to study the effect of Coulomb interaction between localized electrons in disordered systems showing the appearance of an energy gap. Such a Coulomb gap was experimentally discovered some time much later. He was the first to investigate the correlation contribution to the surface energy of metals. His other work worth noting in condensed matter physics is the prediction of electron crystallization of inversion layers, a prediction experimentally verified many years later. His first work in astrophysics was the novel idea of 'recycled pulsars', which resolved mysteriously on the unusual parameters of the famous binary pulsar. His subsequent work on the evolution of supernova remnants drastically modifying the conventional picture has been fully vindicated by x-ray and radio observations. He was the first to publish the detailed theoretical scenario for the origin and evolution of millisecond pulsars. The many predictions made concerning the population of millisecond pulsars have been confirmed by observations during last two decades. The prediction made more than twenty years ago that the millisecond pulsars will turn out to be a new population of Gamma ray sources has been confirmed by the recently launched Fermi Space Telescope. He was the first to propose a novel mechanism for the decay of magnetic fields of neutron stars involving the interaction between the super fluid and super conducting states in their interior.


Prof. Srinivasan was elected as the fellow of Indian Academy of Sciences in 1984. He was IBM Fellow during 1971-72.; Jawaharlal Nehru Fellow during 2007-08.

Awards & Distinctions

Prof Srinivasan is the recipient of K S Krishnan Gold Medal; Jagirdar of Arni Gold medal and University of Madras PE Subramani Iyer Gold medal in 1964. He was the President of Commission 44 on High Energy Astrophysics of International Astronomical Union during 1997-2000; Division XI of the IAU on space and high energy Astrophysics 2000-03 and also the President of Astronomical Society of India between 2000-03.


Photography, listening to western and Indian classical music, hiking are the hobbies of Prof. Srinivasan.
