Dr. Jennifer Schrack is Assistant Professor of Epidemiology at Johns Hopkins Bloomberg School of Public Health (JHSPH). Dr. Schrack holds a joint position with the Krieger School of Arts and Sciences, and she is affiliated with several Centers including the Center for AIDS Research, the Johns Hopkins Center on Aging and Health, the Multicenter AIDS Cohort Study, and the Welch Center for Prevention, Epidemiology and Clinical Research.
Dr. Schrack's primary area of research is the epidemiological assessment of physical activity and its associations with health and longevity in older populations. In collaboration with the SMART group from the JHSPH Department of Biostatistics, Dr. Schrack is working to establish methods to analyze and translate heart rate and accelerometry data into accurate and reliable measures of physical activity in older populations. In recognition of these efforts, Dr. Schrack was recently awarded a 2017 Johns Hopkins University Catalyst Award and a U01 from the National Institute on Aging.
