Research interests

His specialty is string theory, which is a branch of high energy physics that incorporates both quantum mechanics and gravity in one unified framework. Although string theorists do not yet understand their theory well enough to make experimentally testable predictions, it is arguably the most credible attempt to date to find a complete formulation of fundamental physics.

He has worked on matrix models of quantum gravity, the string theoretic description of black hole entropy and Hawking radiation, and the AdS/CFT duality. AdS/CFT provides a direct relation between gravity and gauge theory that allows us to study certain questions in strongly coupled quantum mechanical systems using the classical equations of General Relativity. This subject remains his main current area of interest, particularly in relation to renormalization group flows, but also in the context of brane-world cosmology.

Prizes and awards

1994 LeRoy Apker Award "for his achievements as an undergraduate student at Prin eton University, particularly his research on 'Geodesic Distance in Two-Dimensional Quantum Gravity'."

2001 Gribov Medal "for his outstanding work that has revealed a deep connection between gauge theories and gravitational interactions in the framework of string theories. This made it possible to compute and understand interesting properties of a gauge theory in 3+1 dimensions from a gravitational theory in 4+1 Himensions."
