C. S. Unnikrishnan is a professor of physics at the Tata Institute of Fundamental Research (TIFR), Mumbai, India. His research interests are fundamental issues in gravity and quantum physics, and novel metrology. He was a visiting scientist at the Kastler-Brossel Laboratory, École Normale Supérieure, Paris. The first Bose-Einstein condensate in India was produced in his laboratory at TIFR. Prof. Unnikrishnan’s major contribution is the paradigm of Cosmic Relativity, a theory of relativity and dynamics based on the factual gravity of the matter in the Universe, supported by many experimental results. Recently, he formulated a completion of Hamilton’s action mechanics to a universal mechanics, solving the foundational problems of quantum mechanics. Prof. Unnikrishnan is a proposer-member of the LIGO-India project, for a Laser Interferometer Gravitational-Wave Observatory in India, and a member of the LIGO Scientific Collaboration that detected the gravitational waves. His other interests are music and films, especially the structure and process of their creation.
