Current Research

Ergodic group theory was launched with recent development of the theory of discrete groups and is rooted in unitary representation theory and the theory of von Neumann algebras. I am interested in ergodic actions of discrete groups on measure spaces and the associated orbit equivalence relations, and study them through functional analytic or geometric properties of groups.
