Dr. Meyer is Assistant Professor of Neurology. She received her Ph.D. in Social Psychology from UC Davis and completed a postdoctoral fellowship there and at UCSF. Dr. Meyer’s research interests focus on social determinants of health as they affect underrepresented populations, in particular racial/ethnic minorities and older adults. She is currently examining neighborhood effects on health and she plans to continue this unique aspect of research.

Having been trained as a social psychologist and collaborating with scholars from multiple disciplines (e.g., clinical and community psychology, neuropsychology, epidemiology, sociology, medicine, psychiatry), her research emphasizes the importance of utilizing innovative and interdisciplinary approaches to studying cognitive and mental health.
