Prof. Ruth Kellerhals, Mathematikerin


Biography

As a child, she went to a gymnasium in Basel and then studied at the University of Basel, graduating in 1982 with a diploma directed by Heinz Huber "On finiteness of the isometry group of a compact negatively curved Riemannian manifold". She received her PhD. in 1988, from the same university, with a thesis entitled "On the volumes of hyperbolic polytopes in dimensions three and four". Her advisor was Hans-Christoph Im Hof. During the year 1983-84 she also studied at the University of Grenoble (Fourier Institute).

In 1995 she received her habilitation from the University of Bonn, where she worked at the Max Planck Institute for Mathematics since 1989 until 1995. There, she was an assistant with Professor Friedrich Hirzebruch. Since 1995 she has been an assistant professor at the University of Göttingen, and since 1999 a distinguished professor at the University of Bordeaux 1. In 2000 she became a professor at the University of Fribourg, Switzerland, where she was in 1998 and '99 as a visiting professor.

Research

Her main research fields include hyperbolic geometry, geometric group theory, geometry of discrete groups (especially reflection groups, Coxeter groups), convex and polyhedral geometry, volumes of hyperbolic polytopes, manifolds and polylogarithms. She does historical research into the works and life of Ludwig Schläfli, a Swiss geometer.

She has been a guest researcher at MSRI, IHES, Mittag-Leffler Institute, the State University of New York at Stony Brook, RIMS in Kyoto, Osaka City University, ETH Zürich, the University of Bern and the University of Auckland. Also she visited numerous research institutes and universities in Helsinki, Berlin and Budapest.
