We are studying the electronic structures of new and advanced materials. We are using synchrotron radiation to perform soft x-ray emission and absorption spectroscopy of systems like biomaterials, superconductors and transition metal compounds.

Research Projects

Fundamental Material Properties

I have been focused on characterizing the electronic structure of a series of next-generation phosphors destined for pc-LED applications. The electronic structure of these materials is determined by comparing experimental X-ray absorption, emission and scattering data to theoretical predictions derived within the framework of density functional theory. The ultimate goal is to develop a deeper understanding of the structure-property relationships of these phosphors, in order to facilitate the tailoring of their emission properties. Combining the curiosity-driven study of these novel materials with the prospect of substantial reductions in global energy consumption through the replacement of traditional lighting means with pc-LEDs, this is an exciting and current field of research.
