Research Interests

My research interests are in orthogonal polynomials and operator theory. In particular, I am interested in exploring what properties of orthogonal polynomials are preserved under perturbations of their corresponding linear functionals. I am also curious about the the roles of orthogonal polynomials in semigroup theory and their connections with stochastic processes.
