Subir Sarkar

Professor of Physics

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. 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 - as Glasstone Research Fellow, then PPARC Advanced Fellow, appointed University Lecturer (1998-) and Professor (2006-). Presently I am Affiliated Professor at the Niels Bohr Institute, Copenhagen (where I held a Niels Bohr Professorship 2013-18), and also Adjunct Professor at the Raman Research Institute, Bangalore.

My research interests are mainly at the interface of fundamental physics with astrophysics & cosmology - dark matter & dark energy, inflation & the cosmic microwave background, neutrinos & other relic particles, primordial nucleosynthesis, etc. I also work on high energy cosmic rays, neutrinos & \gamma-rays, and belong to the IceCube Neutrino Observatory and the Cherenkov Telescope Array collaborations. Previously I have worked on the Pierre Auger Observatory & the BEBC Beam Dump experiment at CERN. I also participate in laboratory experiments using high powered lasers to investigate astrophysical processes & fundamental physics.
