She teaches introductory and inorganic chemistry as well as an interdisciplinary course on the chemistry of materials used in artwork. Her research in synthesis and detailed structural characterization of oxide-based materials, including those that form as corrosion products on lead-rich objects, is supported by the National Science Foundation and the Camille and Henry Dreyfus Foundation. Catherine was a postdoctoral fellow at the Cornell Center for Materials Research and the Chalmers University of Technology in Göteborg, Sweden.
