Director & Principal Investigator
Kristine Yaffe, MD
Professor Kristine Yaffe is the Scola Endowed Chair and the Epstein Chair and Vice Chair, Distinguished Professor of Psychiatry, Neurology, and Epidemiology, and Director of the Center for Population Brain Health at the University of California, San Francisco (UCSF). Professor Yaffe is an internationally recognized expert in the epidemiology of dementia and cognitive aging. She serves as PI of almost a dozen NIH, Department of Defense, Veterans Administration, and foundation grants and is a foremost leader in identifying modifiable risk factors for dementia that serve as a foundation for prevention. Dr. Yaffe and her colleagues were the first to determine that potentially 30-40% of dementia risk is preventable. She pioneered early investigations on the roles of estrogen, physical activity, and cardiovascular factors in dementia risk, and more recently, her research group has led work on the connections between Alzheimer disease and other dementias and traumatic brain injury, sleep disorders, and life course exposures. With over 800 peer-reviewed articles dedicated to improving population brain health (H-index=180), her work has formed the cornerstone for dementia prevention trials worldwide. Recently, she and her colleagues completed the first ever comprehensive risk reduction trial in the US and found important cognitive benefits for those who reduced their risk factors for dementia.
In recognition of these groundbreaking accomplishments. Dr. Yaffe has received several prestigious honors including the American Academy of Neurology’s Potamkin Prize for Alzheimer’s Research in 2017, election to the National Academy of Medicine in 2019, the NIH Robert S. Gordon, Jr. Award in Epidemiology in 2021, and the Department of Veterans Affairs John B. Barnwell Award for Achievement in Clinical Research in 2022.
