Robert J. Zimmer is president of the University of Chicago. He is the author of two books, Ergodic Theory and Semisimple Groups and Essential Results of Functional Analysis and more than eighty mathematical research articles.
"""Zimmer is one of the most influential contemporary American mathematicians. The corpus of Zimmer's contributions stands out by its coherence and its grand vision. Much more than being a strong problem-solver, more even than being a theory-builder, Zimmer is a mathematician with an overarching sense of the destination, with a domineering command of all relevant available techniques, with the inspiration to bring to life those techniques that were not available yet, with, in conclusion and to use a trivial formulation, a program.""--Nicolas Monod, cole polytechnique f d rale de Lausanne --Nicolas Monod, cole polytechnique f d rale de Lausanne"
