Caroline M. Tanner
Director of Clinical Research

Dr. Tanner completed a residency in Neurology and fellowship in Clinical Neuropharmacology and Movement Disorders at Rush University and a doctorate in Environmental Health Sciences at the University of California - Berkeley. Her clinical practice specializes in movement disorders, particularly Parkinson’s disease (PD), atypical parkinsonism and dystonia. Her research interests include investigations of descriptive epidemiology, environmental and genetic determinants, biomarkers, early detection, non-motor disease features and interventions for the secondary prevention, disease modification and symptomatic treatment of movement disorders and neurodegenerative diseases.

Dr. Tanner serves as advisor to many scientific, governmental and voluntary groups. Her honors include the Parkinson’s Disease Foundation Outstanding Woman Parkinson’s Disease Researcher in 2004 and the University of California-Berkeley Alumni Association Award for Excellence in Achievement in 2008. Dr. Tanner is also the recipient of the prestigious 2012 Movement Disorders Research Award from the American Academy of Neurology.

Grace Bhudhikanok, PhD
Staff Scientist

Dr. Bhudhikanok earned her Ph.D. in Epidemiology from Stanford University in 2005 with a dissertation on accuracy of recall for lifetime exposures and on bone density. She has been involved with clinical research for almost twenty years, recently with particular emphasis on data rectification and analysis.

Stephanie W. Cash, PhD, MPH
Staff Scientist

Dr. Cash earned her PhD in Epidemiology from the University of Washington (UW) in 2012, after completing her MPH (also at UW) in 2009. Her academic studies and research focused on physical activity, dietary behaviors, DNA damage and repair, cancer prevention, and quality of life. As a Staff Scientist at the Parkinson’s Institute, Dr. Cash works as part of a multidisciplinary team researching Parkinson’s disease (PD) and other movement disorders, with an emphasis on design, conduct, and analysis of clinical trials and epidemiologic studies. Examples of Dr. Cash’s current projects include investigating dietary risk factors for parkinsonism among Alaska Native people and the analysis of low heart rate variability (HRV) as a potential pre-motor PD identification tool.
