Igor R. Klebanov is the Eugene Higgins Professor of Physics and the director of the Princeton Center for Theoretical Science at Princeton University. He earned his Ph.D. in theoretical high-energy physics from Princeton University in 1986. After completing post-doctoral work at the Stanford Linear Accelerator Center in 1989, Klebanov has been on faculty at Princeton. His research interests include quantum field theories and their dual descriptions by higher dimensional theories that include gravity, such as the Anti-de Sitter/Conformal Field Theory correspondence. Klebanov is also interested in the physics of strong nuclear interactions, and he is the director of the Simons Collaboration on Confinement and QCD Strings. Klebanov is the recipient of numerous awards and honors, including the 2022 Oskar Klein Memorial Lecture and Medal from Stockholm University and the 2023 Dirac Medal from the International Centre for Theoretical Physics, in Trieste, Italy. He has been elected to the United States National Academy of Sciences and the American Academy of Arts and Sciences.
