Research Interests and Projects

Electron paramagnetic resonance of irradiation damage in organic solids of biological interest, of defects in insulators and ionic solids, and of sickle cell hemoglobin . The studies of irradiated protein focus on the mechanism through which random damage from X-rays migrate to sulfur atoms or to the glycine residue.
