Research Interests

I closed my research laboratory in June 2011 after 31 years as an NIH and Juvenile Diabetes Foundation supported investigator and have focused subsequently on clinical neuropathology. I have recently been working on the development of an online atlas of neuropathology. Currently, I am a collaborator with NIH supported investigators who are interested in peripheral nerve disease, the treatment and prevention of radiation injury, neuroimmune and neuroinfectious neuropathology, microglial pathology, and neurodegenerative diseases.
