Daya Shankar Kulshreshtha

Daya Shankar Kulshreshtha (born December, 1951) is an Indian theoretical physicist, specializing in formal aspects of quantum field theory, string theory, supersymmetry, supergravity and superstring theory, Dirac's instant-form and light-front quantization of field theories and D-brane actions. His work on the models of gravity focuses on the studies of charged compact boson stars and boson shells. He was several times visiting faculty in the Nuclear Theory Group of Iowa State University and in the Field Theory Group of the Institute of Theoretical Physics, University of Oldenburg.

Research Kulshreshtha's research focuses on formal aspects of quantum field theory, string theory, supersymmetry, supergravity and superstring theory. In particular, he studies the canonical structure, constrained dynamics and Dirac's instant-form and light-front quantization of field theory, string theory and D-brane actions using the Hamiltonian and path integral formulation and the BRST quantization. His work on the models of gravity and general relativity, focuses on the studies of charged compact boson stars and boson shells. This work suggests that an infinite sequence of bifurcation points exists in the phase diagrams of such boson stars.
