Dr. Ooguri is a theoretical physicist working on quantum field theory, quantum gravity, and superstring theory. His research strategy is to discover mathematical structures in these theories and to exploit them to invent new theoretical tools to solve fundamental questions in physics.

In particular, he developed the topological string theory to compute Feynman diagrams of superstring theory and used it to solve mysterious quantum mechanical properties of black holes. He also worked on conformal field theory in two dimensions, D branes in Calabi-Yau manifolds, the AdS/CFT correspondence, and properties of supersymmetric field theories and their relation to superstring theory.

"Strings" is the most important annual conference in string theory and has been held every year since 1995.

Ooguri has given invited talks at the following Strings Conferences.
