Christopher M. Ryan, Ph.D. Dr. Ryan is interested in the effects of various medical disorders and medical therapies on cognitive functioning in both children and adults. He is currently involved in the first study of diabetic patients to delineate changes in cognitive functioning from late childhood into middle-adulthood. This study is also the first to link functional changes to diabetes-related biomedical variables.
