Utkal University, Bhubaneswar 1989 Brief writeup on area of specialization/awards/achievements: Works have been done in the domain of space-time gauge theories, conformal field theories, (supersymmetric) quantum groups, non-commutative field theories, W-Algebra, integrable models, non-linear realizations, superfield formalism, etc. Currently, we are devoting time on the study of higher p-form (p = 2, 3, 4) gauge theories within the framework of BRST and superfield formulations. These gauge theories have become quite popular because of their relevance to the modern developments in theories of (super) strings and extended objects. Some exciting works have been done at BHU on (non-) Abelian 2-form and 3-form gauge theories. This direction is being pursued at the moment at BHU and exciting results are expected to ensue in due course of time. Our works are totally analytical and these are not dependent on computer programming and machines of any kind.
