Research Interests

I am interested in the use of operator theoretic techniques to solve problems in functional analysis in several variables. In particular, I am interested in generalizing theorems of classical complex analysis concerning important families of analytic functions to the several variable case. I am also investigating functions in non-commuting variables with properties that make them natural on matrix inputs.
