My research addresses a broad variety of problems from analysis, geometry and probability. Particular foci in recent years had been questions of optimal transport and effects of curvature in various contexts, including Riemannian manifolds, Finsler spaces, and infinite dimensional spaces (like path spaces, loop spaces, configuration spaces, or spaces of measures). With foundational publications I contributed to establish and to promote a new hot area in mathematics: metric measure spaces with synthetic Ricci bounds. Other research topics are matching problems, random measures, interacting particle systems and their scaling limits, gradient flows, geometric and functional inequalities, stochastic calculus on manifolds.
Major research directions for the future include: precise geometric structure of metric measures spaces with curvature-dimension condition (singular/regular points, boundaries) and their relation to Cheeger-Colding limits and Alexandrov spaces, analysis on time-dependent mm-spaces and their evolutions (e.g. under generalizations of Ricci flow), extension of ‘curvature’ concepts to spaces which so far had been out of reach (including branching or non-convex boundary conditions), stochastic calculus on mm-spaces, higher dimensional random geometries.
