Wendelin Werner is a German-born French mathematician working on probability theory. His research deals with random continuum objects and relates to questions originating from physics.
His results for random structures in the plane (with co-authors Lawler, Schramm, Smirnov or Sheffield) include the proof of a conjecture by Mandelbrot stating that the fractal dimension of the outer boundary of a Brownian path is 4/3, the computation of critical exponents for percolation, the determination of the scaling limit of uniform spanning trees, and the construction and study of conformal loop ensembles.
Among the awards he received for his work are the Fermat Prize, the Pólya Prize, the Fields Medal and the Gumin Prize. He is a member of the French Academy of Sciences, the Leopoldina and the Berlin-Brandenburg Academy of Sciences.
