College of Liberal and Fine Arts


Dr. Sandra Morissette is a clinical psychologist and Professor in the Department of Psychology at UTSA. For over 18 years, she worked as a clinician and researcher in both the Veterans Health Administration and universities settings, dedicating her career to treating and researching ways to improve the lives of post-9/11 veterans. Her expertise is in studying trauma, anxiety, and addictive behaviors, with a particular interest in understanding factors that improve functional recovery in veterans who served in support of the wars in Iraq and Afghanistan. For the last 7 years, she conducted a series of three longitudinal studies that investigated warzone experiences, traumatic stress, and long-term functioning in returning veterans. The aim of these studies is provide a scientific platform for developing novel interventions for veterans who are struggling with recovery and reintegration. As a UTSA faculty member, Dr. Morissette has a special interest in helping student veterans in higher education capitalize on the GI Bill and reset their missions as productive civilians. She recently conducted an open pilot clinical trial of Written Exposure Therapy for students with post-traumatic stress disorder. Delivering empirically-supported treatments in real-world settings, such as UTSA’s Counseling Services, is a critical aspect of her research mission to bring services to patients where and when they need them.
