From May 19 to 23, 2025, the Centre International de Rencontres Mathématiques (CIRM) hosted the conference “Probability, Finance, and Signal” in celebration of Professor René Carmona’s birthday and distinguished career. Held in Marseille, Prof. Carmona’s hometown, the event brought together international experts working in fields to which he has made influential contributions, including stochastic analysis, probability theory, and their connections to partial differential equations. Particular emphasis was placed on mathematical models of interacting rational agents in mean-field frameworks with applications to financial mathematics, as well as on signal theory, a long-standing area of his research.

Professor Carmona has been a member of Princeton University’s faculty since 1995, serving as a professor in the Department of Operations Research and Financial Engineering (ORFE), where he also served as department chair from 2015 to 2018. He is also affiliated with various academic units across Princeton. Over the past decade, his research has helped shape the field of Mean Field Games and Mean Field Control, emphasizing a probabilistic approach to these complex systems. Among other distinctions, his influential two-volume book on the subject, co-authored with François Delarue, received the J.L. Doob Prize from the American Mathematical Society, recognizing its outstanding contribution to mathematical literature.
