“Understanding the contributions of vascular health to normal and pathological aging is fundamentally important given both the prevalence of vascular risk in the aging population and its amenability to prevention and treatment.”

Research interests:

Keywords: cognitive aging, structural and functional changes with age, amyloid imaging, impact of health on brain aging, genetic influences on aging, individual differences

Dr. Rodrigue's research focuses on mapping the changes that the healthy human brain undergoes with aging and understanding how these changes affect behavior. She is specifically interested in how health factors such as hypertension in combination with genetic risk can shape the course of aging. Our lab uses a variety of tools to asses brain and cognitive aging including structural and functional MRI, beta-amyloid PET imaging and detailed cognitive and neuropsychological assessment.
