Past IPM Positions

PostDoctoral Associate, School of Physics (2006 - 2010) (December 2006-December 2008 )

Research Interests

Mathematical aspects of string theories, application of string theories to gravity and cosmology and theory of elementary particles.Gravity and Cosmology, HEP

Research Activities

I study string theory and its applications to cosmology, theory of elementary particles and gravity. I have computed the worldsheet corrections to the entropy of black holes and T-duality in the Heterotic String Theories. Currently I am calculating the first non-trivial worldsheet corrections in II13 Theory to examin the validity of the OSV conjecture for the entropy of black holes.

Present Research Project at IPM

The perturbative world sheet corrections and the OSV conjecture
