Dr. Simonsick is an epidemiologist and staff scientist in the Longitudinal Studies Section of the Translational Gerontology Branch within the Intramural Research Program (IRP) of the National Institute on Aging (NIA) and an associate professor in the Division of Geriatric Medicine and Gerontology at the Johns Hopkins University School of Medicine. She also serves as affiliated faculty for the Johns Hopkins Center on Aging and Health (COAH). For over 35 years she has conducted aging-related research within the context of longitudinal observational studies and has substantial expertise in the design, conduct and administration of multi-disciplinary longitudinal studies of aging. Currently, she is Co-Director of the Baltimore Longitudinal Study of Aging (BLSA) and Principal Investigator and Federal Project Officer of the Health, Aging and Body Composition (Health ABC) study.
Her primary areas of expertise include assessment of higher-order physical function including endurance walk performance and fatigability and changes with aging. She also has substantial interest and experience in evaluating the behavioral, psychological, biomechanical and physiologic factors and conditions that impact energetic cost and reserve capacity and how these in turn impact maintenance and decline in function and the overall aging process. She has extensive knowledge of proper design and conduct of longitudinal observational studies of aging and aged individuals and appropriate analysis techniques. She has established a broad network of domestic and international collaborators, with activities ranging from a close mentoring role to shared expertise towards development and completion of both specific manuscripts and substantial large-scale initiatives.
