I work on Quantum Field Theory almost exclusively these days, focusing on geometric and algebraic aspects of renormalization, quantization of constrained systems, dual descriptions of field theories, etc., in the context of theories of the antisymmetric tensor field. In the past I have also worked on gravitational physics, mainly exact black hole and cosmological solutions, and would like to get back to some of that fairly soon.

I have recently written a book jointly with Palash B. Pal. It is called `A first book of Quantum Field Theory', published by Narosa Publishing House. You can download the Table of Contents and Preface (ps file) from here. The errata are here. These corrections have been incorporated into the second edition. You can also order the book from amazon.com.
