IceCube

Physics World 2013 Breakthrough of the Year
IceCube at Oxford

I am a member since 2004 of the IceCube collaboration which discovered cosmic high energy neutrinos and identified some of their astrophysical sources.

IceCube @ Oxford

I am an alumnus of the Indian Institute of Technology, Kharagpur (1969-74) and received my PhD (1982) at the Tata Institute of Fundamental Research, Bombay, where I was staff member 1979-84. Subsequently I held visiting positions at CERN, Oxford Astrophysics, Rutherford Appleton Laboratory, and worked in science education for the NGO Eklavya, Bhopal. Since 1990 I have been at the Rudolf Peierls Centre for Theoretical Physics, Oxford - as Glasstone Research Fellow, then PPARC Advanced Fellow, appointed Lecturer in 1998 and Professor in 2006. I was Head of the Particle Theory Group (2011-19) and Niels Bohr Professor at Copenhagen (2013-18). I am an Emeritus Fellow of Linacre College.

CV & Publications

My interests lie at the interface of fundamental physics with astrophysics and cosmology: big bang nucleosynthesis, dark matter, dark energy, inflation & the cosmic microwave background,  relic topological defects, weak interactions & neutrinos etc. I also work on high energy cosmic rays, gamma-rays & neutrinos, and belong to the IceCube Neutrino Observatory and the Cherenkov Telescope Array collaborations. (Earlier I worked on the Pierre Auger Observatory and the CERN BEBC Beam Dump.) I participate in laboratory experiments using high powered lasers to investigate astrophysical processes, in the programme on Quantum Sensors for Fundamental Physics, and am a member of the Dark Energy Science Collaboration, Rubin Observatory.

To celebrate my 70th birthday, my ex-students & collaborators held a 'fest' ...

I am married to Amanda Cooper-Sarkar - artist and particle physicist (we have a few joint publications).
