As a PhD candidate in Mathematics, Katherine Heller’s research interests lie in the area of function-theoretic operator theory. Specifically, she studies composition operators on spaces of analytic functions. She has taught first and second semester courses of Calculus and has also been involved in the Girls and Mathematics Summer Program, which works with middle school girls to foster an enthusiasm for mathematics. As a GSA, Katherine looks forward to working with graduate students from all disciplines to encourage positive classroom experiences.
