Jane Wegschneider Hyman, Ph.D., a researcher and writer on women's health, contributed to both Ourselves, Growing Older and The New Our Bodies, Ourselves. She is author of two other books. Over the years, her interest has shifted from physical to mental health, partly through her own experiences with obsessive-compulsive disorder and depression, and partly because of her prior work on seasonal affective disorder, anorexia, and bulimia. During her graduate studies in psychology, she specialized in mental health problems that primarily afflicted women.
