My research interest concerns the interactions between operator algebras, group theory, and algebraic topology.  More specifically,  I have studied the Baum-Connes assembly map for certain discrete groups involving their K-theory and (Davis-Lück’s picture of) equivariant K-homology. Moreover, I have been working on simplicity and the unique trace property of  group Lp-operator algebras.
