He is a theoretical condensed matter physicist focused on understanding materials for use in high efficiency conversion and detection of light. Developing new materials to allow novel high efficiency devices requires insight into the electronic properties of materials, especially in the presence of the nearly-unavoidable disorder in real systems. A variety of techniques, including phenomenological models of materials and higher-level device models, are used to describe material properties and predict new useful structures. Dr. Krich received his PhD in Physics from Harvard University and was a Ziff Postdoctoral Fellow of the Harvard University Center for the Environment, in the Department of Chemistry and Chemical Biology.
