My current research focuses on the Baum-Connes conjecture, including its connections to Kazhdan’s property (T). More generally, I am interested in the interaction between operator algebras, group theory, and algebraic topology, with the first one being in the centre. In my dissertation, 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. Previously, I have been working on simplicity and the unique trace property of  group Lp-operator algebras.
