Dr Pankaj S. Joshi

Dr Pankaj Joshi, an internationally acclaimed scientist, was a Senior Professor in the department of Astronomy and Astrophysics at the Tata Institute of Fundamental Research, Mumbai, before joining CHARUSAT as their Provost, and Founding Director for the International Center for Cosmology (ICC). More popularly, he is regarded as a scholar, physicist, and an expert on cosmology.

Professor Joshi’s research interests are general relativity and cosmology. He has made fundamental contributions in black hole physics and gravitation theory. His extensive analysis of general relativistic gravitational collapse has been widely recognized as providing significant insights into the final fate of massive collapsing stars in the universe, formation of space-time singularities, and cosmic censorship. His research, which mainly revolves around Cosmology and Gravitation Physics, has been reported in more than 200 research papers in International Journals of repute, and also in monographs from OUP (Oxford) and CUP (Cambridge), and other books on the subject.

He has held visiting faculty positions in several countries doing research and lecturing on these topics and has won several awards as well as Fellowships to scientific academies. He has been an adjunct faculty, fellow and visiting scientist to Cambridge University, UK; Harvard University, USA; New York University (NYU), USA; University of Pittsburgh, USA; University of Southampton, UK; Osaka City University,Japan; University of Basque Country, Spain; University of Natal, South Africa; Queen Mary and Westfield College, London; Milano Polytechnic, Italy; and University of Cincinnati, USA, to name a few International ones.

He has also contributed a large number of books and articles towards science outreach and has given many public lectures. He has been awarded with many coveted awards and prizes. Some of these are, the Gravity Research Foundation (USA) award for research work on the Final Fate of Gravitational Collapse (1991) (other winners of the same include M. Turner (NASA/Fermi Lab), S. Coleman (Harvard), L. Krauss (Yale), J. Preskill (Caltech), and F. Wilczek (Princeton)); the Prof A C Banerji Gold Medal and Memorial Lecture award by the National Academy of Sciences (NASI); C V Raman lecture award by the Department of Atomic Energy (DAE).
