The 2023 Rollo Davidson Prizes are awarded to IMS member Duncan Dauvergne (University of Toronto), for outstanding contributions to the theory of random sorting networks and for the construction and study of the directed landscape; and to Nina Holden (New York University) and Xin Sun (University of Pennsylvania) for leading work on random planar maps and Liouville quantum gravity. The Prizes have been awarded annually to young probabilists since 1976.
