She is Chief of the Division of Reproductive Science in Medicine, Feinberg School of Medicine and Professor of Molecular Biosciences at the Weinberg College of Arts and Sciences. In 1993, The National Institute of Health (NIH) Revitalization Act mandated inclusion of women in clinical research. Still, two decades later – only 37% of clinical human studies include women.
