Dr. Melinda C. Power is an Associate Professor of Epidemiology at the George Washington University (GWU) Milken Institute School of Public Health, and was a 2022-2023 Health and Aging Policy Fellow.  Dr. Power has expertise in statistical analysis of observational data, and a commitment to improving epidemiologic methods in the study of late-life cognition and dementia.  Her current research is designed to inform clinical practice and health policy around supporting people living with dementia.

Dr. Power is also the founding Director of the GW Institute for Brain Health and Dementia.  The Institute aims to promote and support research on cognitive health that will meaningfully impact lives, through promotion of brain health, prevention of cognitive loss, addressing disparities in cognitive health, and improving the quality of life of persons living with dementia and their care partners.
