Bio

Kelsey Thomas is an Assistant Professor of Psychiatry at UC San Diego School of Medicine and a Research Health Scientist at VA San Diego. She completed her doctoral training at University of Florida and completed her predoctoral internship and postdoctoral fellowship at VA San Diego/UCSD. Together with Dr. Katherine Bangen, they run the Neuropsychology of Vascular Aging and Alzheimer’s (NOVAA) Lab.

Dr. Thomas’s research focuses on the preclinical and prodromal phases of Alzheimer’s disease and vascular cognitive impairment and understanding the best approaches for capturing subtle cognitive declines. She integrates biological markers (e.g., plasma, PET, CSF, MRI) of Alzheimer’s disease, vascular disease, and neurodegeneration into her work to better understand possible mechanisms of subtle cognitive changes.

Dr. Thomas studies early cognitive changes associated with diabetes and other vascular risks as well as sociocultural factors that impact cognitive aging outcomes. Her research is funded by NIH/NIA, Department of Veterans Affairs Clinical Services Research and Development, and the Alzheimer’s Association.
