Marcia Stefanick, PhD
Director and Co-Founder, Stanford WHSDM Center (Women's Health & Sex Differences in Medicine)
Marcia Stefanick, renowned women’s health researcher who chaired both the executive and steering committees of the Women’s Health Initiative (the largest study of women ever done in the United States), has been involved in the Women’s Health at Stanford program since its inception, in 2001.
Dr. Stefanick’s research, which has been widely disseminated nationally and internationally, has emphasized the role of lifestyle — especially exercise, diet, weight control, and menopausal hormone therapy — on chronic disease prevention, particularly heart disease, breast cancer, osteoporosis, and more recently, dementia. Her primary academic interests include sex/gender differences and the influence of sex hormones on human physiology and disease, menopause, and health promotion over the life course, including healthy aging.
In addition, she is an experienced and active mentor of junior faculty, and teaches courses to both medical students and undergraduates on the role of sex differences in physiology and disease, and current topics in women’s health.
