Isabel Sible, PhD, MA

Clin Neuropsychology Fellow

Isabel joined the Clinical Affective Neuroscience (CAN) Laboratory at UCSF’s Edward and Pearl Fein Memory and Aging Center in September 2024 as a postdoctoral fellow in neuropsychology. She earned her PhD in clinical psychology from the University of Southern California and completed her predoctoral internship in geriatric neuropsychology at the Palo Alto VA. During her graduate studies, Isabel explored the relationships between physiological functioning—particularly blood pressure—and brain aging, as well as the risk of cognitive decline.

Alison Walmsley

Clinical Research Coordinator

Alison Walmsley is a Clinical Research Coordinator at the UCSF Edward and Pearl Fein Memory and Aging Center, where she works on the Advancing Diagnosis of Dementia in Primary Care Practice (ADDPCP) study, a multi-year project funded by the National Institute on Aging.
