Gali Weissberger, PhD

Postdoctoral Scholar

Dr. Gali Weissberger is a postdoctoral fellow in the Han Research Lab. She received her doctorate in Clinical Psychology with an emphasis in neuropsychology from the San Diego State University and University of California, San Diego, Joint Doctoral Program in Clinical Psychology in 2015. She completed her pre-doctoral clinical internship with a neuropsychology emphasis at the VA Boston Healthcare System's psychology internship program. She also completed a two-year research fellowship at the West Los Angeles VA Hospital. Gali is interested in understanding protective and deleterious factors that moderate an individual's risk of developing Alzheimer's disease utilizing neuroimaging, neuropsychological, and behavioral techniques. In graduate school, she focused her dissertation on the impact that bilingualism and other cultural factors have on the development and progression of Alzheimer's disease in Hispanic older adults. During her fellowship at the West LA VA, she investigated the impact of health risk factors such as inflammatory disease on the abnormal aging process, and explored the neural correlates of mood disorders in Alzheimer's disease. Gali is looking forward to continuing to pursue her research endeavors in the Han Research Lab.
