She directs a multi-center study to determine the impact of maternal remission from depression on offspring. She is participating in several studies of the genetics of mood and anxiety disorder. She directs a study of psychiatric disorders in a poor minority patient population in primary care. Along with her late husband, Gerald Klerman, she developed and tested interpersonal psychotherapy (IPT). Her book outlining the method has been translated into 5 languages.
