Welcome to my web page. My name is Ashoke Sen and I work at the Harish-Chandra Research Institute in Allahabad.

My area of research is string theory, -- a theory that tries to give a unified description of all matter and the forces between them based on the postulate that the elementary constituents of matter are tiny one dimensional (string-like) objects instead of point particles. My specific research interests include S-duality, tachyon condensation and black hole entropy.
