Research and Clinical Interests

My clinical interest is that of the diagnosis of diseases of the central nervous system and peripheral nervous system, with an emphasis on neoplastic and infectious disease. This includes translational research with neuro-oncology, and a spectrum of studies with the brain tumor research center.

Research interests include cytogenetics of CNS neoplasms and molecular control mechanisms (collaboration with Dr. Anita Lal and Dr. Joseph Costello). With Dr. William Young I am currently studying cellular processes influencing the development of CNS vascular malformations. With Dr. Robert Higgins of the UC Davis School of Veterinary Medicine I have been identifying a number of animal brain tumors, working on the development of animal tumor model systems, and developing potential therapeutic approaches.
