ICTP has awarded its 2023 Dirac Medal to four physicists who have made wide-ranging contributions to string theory, a mathematical framework in fundamental physics that aims to describe the entirety of the whole universe. 

The 2023 Dirac Medallists are:

• Jeffrey Harvey, University of Chicago, USA
• Igor Klebanov, Princeton University, USA  
• Stephen Shenker, Stanford University, USA 
• Leonard Susskind, Stanford University, USA 

The award cites "their pioneering contributions to perturbative and non-perturbative string theory and quantum gravity, in particular, to the aspects related to anomalies, duality, black holes and holography".
