Hirosi Ooguri (spelled as Hiroshi Oguri in government documents^[1]) (大栗 博司, born 1962) is a theoretical physicist working on quantum field theory, quantum gravity, superstring theory, and their interfaces with mathematics. He is Fred Kavli Professor of Theoretical Physics and Mathematics^[2] and the Founding Director of the Walter Burke Institute for Theoretical Physics at California Institute of Technology. He is also the director of the Kavli Institute for the Physics and Mathematics at the University of Tokyo and is the chair of the board of trustees of the Aspen Center for Physics in Colorado.

Ooguri aims at discovering mathematical structures in these theories and exploiting them to invent new theoretical tools to solve fundamental questions in physics. In particular, he developed the topological string theory to compute Feynman diagrams in superstring theory and used it to study mysterious quantum mechanical properties of black holes. He also made fundamental contributions to conformal field theories in two dimensions, D-branes in Calabi-Yau manifolds, the AdS/CFT correspondence, and properties of supersymmetric gauge theories and their relations to superstring theory.^[3]
