Personal profile

Research interests

My research involves the use of soft x-ray spectroscopies to study the electronic properties on a wide variety of materials, of both fundamental scientific importance, and technical significance. The primary areas of research are high resolution x-ray emission, resonant inelastic x-ray scattering, and photoemission from organic thin films.
