QualificationsM.D., McGill University, Medicine, 1989. B.A., University of California, Berkeley, Biochemistry, 1985. Expertise and Research InterestsClinical interests include management of movement disorders, especially Parkinson's disease, dystonia (including treatment with botulinum toxin), and tremor, screening and selecting patients for deep brain stimulation (DBS), managing these patients post-operatively and programming their DBS parameters. Research interests include DBS-related studies, quantitative gait analysis in Parkinson disease, genetic studies in Parkinson disease, and epidemiological studies that involve drugs and neurodegenerative disorders. Teaching activities include training of medical students, residents, and fellows in inpatient and outpatient general neurology, movement disorders, and neurodegenerative disorders.
