Dr. Cauley, DrPH, is a Distinguished Professor and Executive Vice Chair, Department of Epidemiology, Graduate School of Public Health (GSPH), University of Pittsburgh (Pennsylvania). Her primary research interest is the epidemiology of osteoporosis especially the large worldwide ethnic and geographic variability in fracture, osteoporosis screening and treatment, risk factors for fractures and the consequences of osteoporosis in both men and women. Her research has also focused on women's health and aging, falls, the interaction between endogenous and exogenous hormones, risk factors, and disease outcomes. She was principal investigator for several large cohort studies including the Study of Osteoporotic Fractures (SOF) and the Osteoporotic Fractures in Men (MrOS) study. She is a co-investigator for the Study of Women’s Health Across the Nation (SWAN) with particular emphases on skeletal health and physical function and body composition changes, novel measures of hip strength and the trabecular bone score across menopause. She initiated breast cancer follow-up in SOF and was the first to demonstrate an association between bone mineral density (BMD) and breast cancer, suggesting that BMD could be used as a cumulative measure of lifetime exposure to estrogen. Dr. Cauley has authored more than 800 papers for scientific journals and 28, book chapters. She co-edited a book entitled the Epidemiology of Aging, published in 2012.
