My publications date back to 1977 when I began work on my PhD thesis (1982) at the Tata Institute of Fundamental Research, Bombay - initially in experimental cosmic ray physics and then in theoretical high energy astrophysics. In the 1980s I switched to the emerging field of astroparticle physics while at CERN Geneva, Oxford Astrophysics and the Rutherford Appleton Laboratory. Since 1990 I have been in the Rudolf Peierls Centre for Theoretical Physics at Oxford and visited the University of Copenhagen as Niels Bohr Professor (2013-18) . My interests are mainly at the interface of particle physics with astrophysics and cosmology - viz. dark matter & dark energy, inflation & the cosmic microwave background, neutrinos & other relic particles, primordial nucleosynthesis, relic topological defects etc. I also work on high energy cosmic rays, neutrinos and gamma-rays and belong to the IceCube Neutrino Observatory and the Cherenkov Telescope Array collaborations. Previously I have worked on the Pierre Auger Observatory and the CERN-WA66 BEBC Beam Dump experiment. I also participate in laboratory experiments using high powered lasers to investigate astrophysical processes & fundamental physics, and in the LSST/DESC project on the Vera Rubin Observatory.
