The 2023 Class of Fellows of the AMS includes IMS Fellow David Nualart, Black-Babcock Distinguished Professor Emeritus at the University of Kansas. Dr. Nualart was selected, “For contributions to Malliavin calculus, stochastic PDEs, and fractional Brownian motion.” He lists his research interests as stochastic analysis, Malliavin calculus,anticipative stochastic calculus, large deviations, rough path analysis, stochastic partial differential equations, fractional Brownian motion, and mathematical finance. The Fellows of the AMS program recognizes members who have made outstanding contributions to the creation, exposition, advancement, communication, and utilization of mathematics.
