I received my undergraduate education at Yale University, graduating in 1982. I completed my PhD dissertation in 1988 at the University of California, Berkeley under the supervision of Donald Sarason. My main research interests are operator theory, functional analysis, complex analysis, and linear algebra. More specifically, my main mathematical love is the theory of Banach and Hilbert spaces of holomorphic functions and the operators that act on those spaces. Most of my work involves the classical Hardy spaces and de Branges-Rovnyak spaces (Hilbert spaces of holomorphic functions that live inside the classical Hardy space), and on various special operators that act on those spaces (Toeplitz, Hankel, and composition operators).
I am currently serving as the Dean of Studies.
