Sylvia H. Ley, PhD, RD, serves as a tenure-track Assistant Professor in the Department of Epidemiology at Tulane University's Celia Scott Weatherhead School of Public Health and Tropical Medicine. She teaches Epidemiologic Methods I and III while mentoring PhD and MS students in chronic disease research.
Her educational background includes:
- Postdoctoral training at Harvard T.H. Chan School of Public Health focusing on large-scale cohort studies
- Doctoral studies in maternal and infant nutrition and clinical epidemiology at University of Toronto
- Registered Dietitian certification from Sunnybrook Health Sciences Centre
Dr. Ley's research centers on life-course strategies for chronic disease prevention, with emphasis on nutrition, diabetes progression, and cardiovascular risk in women. Her work investigates how reproductive factors (menarche timing, lactation, gestational diabetes), sleep patterns, and dietary behaviors influence long-term metabolic outcomes across the lifespan. She employs advanced epidemiological methods in major cohort studies including NHANES and the Bogalusa Heart Study.
Analysis of her recent publications reveals consistent focus on sex-specific disease pathways and developmental origins of health, particularly examining how early-life exposures manifest as cardiometabolic disorders decades later. Her work bridges clinical epidemiology with nutritional science to identify modifiable risk factors.
Dr. Ley actively mentors graduate students including Santos MP, Mullen AJ, and Siebach MK. Her research receives continuous funding from major agencies including NIH, NSF, and CIHR, supporting her 80+ peer-reviewed publications that have accumulated over 14,000 citations. She serves in leadership roles as Past-Chair of Nutritional Epidemiology for the American Society for Nutrition, Associate Editor for the American Journal of Clinical Nutrition, and co-Chair of the Women's Interprofessional Network for the American Diabetes Association.
