## Research Interests

I work in functional analysis and specialize in the study of algebras of linear operators on Hilbert space. More precisely, I study Banach *-algebras which satisfy the C*-norm identity $\|a^* a\|=\|a\|^2$. A celebrated result of Gelfand and Naimark imples that all such algebras can be realized as algebras of operators on Hilbert space.

I specialize in the study of the fine structure of C*-algebras associated to dynamical systems of various sorts. In particular, I am interested in the fine structure of C*-crossed products, groupoid C*-algebras and more recently groupoid crossed products. While I have also dabbled in noncommuntative duality, most of my work involve Morita equivalence and often continuous-trace C*-algebras.
