Subir Sarkar

Head, Particle Theory Group

I was educated in India, at the Indian Institute of Technology, Kharagpur and obtained my PhD (1982) at the Tata Institute of Fundamental Research, Bombay, where I was a staff member 1979-84. Subsequently I held visiting positions at CERN Geneva, Oxford Astrophysics, Rutherford Appleton Laboratory, and also worked in science education at Eklavya, Bhopal. Since 1990 I have been at Oxford - first as Glasstone Research Fellow, then PPARC Advanced Fellow, appointed University Lecturer (1998) and Professor (2006). I am an Associate of the Discovery Centre and Affiliated Professor in the Astroparticle Physics Group of the Niels Bohr Institute, Copenhagen where I held a Niels Bohr Professorship during 2013-18.

My research interests are at the interface between fundamental physics and astrophysics & cosmology - specifically theoretical aspects of dark matter, inflation and large-scale structure formation, the cosmology of neutrinos and other relic particles, primordial nucleosynthesis, cosmic microwave background et cetera. I work on high energy cosmic rays, neutrinos and gamma-rays and participate in the experiments Pierre Auger Observatory (ended), IceCube Neutrino Observatory and the (forthcoming) Cherenkov Telescope Array. Previously I worked with the BEBC WA66 Beam Dump collaboration at CERN. I am now participating in experiments using high powered lasers to investigate astrophysical processes (e.g. cosmic ray acceleration) and fundamental physics.
