Clinical Psychology: personality traits and psychosocial factors influencing the co-morbidity and maintenance of addictive behavior patterns

Dr. Sarah Fischer received her Ph. D. in clinical psychology from the University of Kentucky in 2006. She completed her pre-doctoral internship and postdoctoral fellowship at the University of Chicago. From 2007 to 2012, Dr. Fischer was an assistant professor of psychology at the University of Georgia. She moved to George Mason University in Fall 2012. Her program of research focuses on how trait impulsivity influences pathology such as binge eating, bulimia nervosa, and subtance abuse, as well as on how this trait influences loss of control over behavior in specific environmental contexts. Currently, Dr. Fischer and her graduate students are completing a study examining the neural correlates of reactivity food cues under acute stress in bulimia nervosa, and how this influences eating behavior in daily life. They are also completing a study of how impulsivity interacts with acute mood shifts to influence decision making and eating behavior. Dr. Fischer collaborates with several members of the psychology department, such as Dr. James Thompson, Dr. Tara Chaplin, and Dr. Christy Esposito-Smythers on studies which utilize neuroimaging and treatment outcome research.

Dr. Fischer will not be accepting a new PhD student for the Fall 2024 application cycle.
