• Dr. Gabriel is cross-trained in exercise physiology and epidemiology with over a decade of experience implementing physical fitness and physical activity measures in large, observational studies. Her research interests focus on two key areas of inquiry. First is the development and evaluation of methodological strategies to optimize the precision of physical fitness, physical activity and sedentary behavior measures for use in population-based studies. The second is to examine the timing of these exposure variables and risk of subsequent disease and disability using a life-course perspective with a strong focus on midlife women. She has served as principal investigator on projects funded by the American College of Sports Medicine (2007-08), American Institute for Cancer Research (2010-12), American Heart Association (2014-15), and National Heart, Lung and Blood Institute (2015-16) and National Institute on Aging (2015-16).

    She also actively collaborates on several large observational studies, providing consultation and support specific to: study design, strategies for physical activity and sedentary behavior assessment, computation/derivation of summary estimates, data reduction and processing of accelerometer data, statistical handling of physical activity and sedentary behavior data, statistical methods to examine associations of physical activity and sedentary behavior with health risk factors and outcomes and data interpretation and dissemination of findings. These collaborations include several large, federally funded prospective cohort studies including Coronary Artery Risk Development in Young Adults, the Study of Women’s Health Across the Nation and Atherosclerosis Risk in Communities. In addition, her scholarly work includes over 100 peer-reviewed publications and four book chapters.
