Gayle Greene is a professor of English at Scripps College, in Claremont, California, where she teaches Shakespeare, contemporary women writers, women's studies, creative nonfiction, and lately, courses on sleep. After writing several books on contemporary women's fiction and feminist theory, her interests shifted to health and the environment, and she published The Woman Who Knew Too Much: Alice Stewart and the Secrets of Radiation, a biography of the pioneer radiation epidemiologist whose research turned up the links between fetal x-ray and childhood cancer. She then turned her research to insomnia, which has been the bane of her existence since she can remember, and began attending American and European sleep conferences. Greene is a member of the American Academy of Sleep Medicine, a professional medical society for researchers and clinicians, and a board member and the patient representative of the American Insomnia Association.
