Dr. Tull obtained his PhD in clinical psychology from the University of Massachusetts Boston in August 2005, where he worked under the mentorship of Dr. Lizabeth Roemer conducting research on emotion regulation and the anxiety disorders. Further, he received training in acceptance- and mindfulness-based treatment approaches. He completed his internship at the Boston Consortium in Clinical Psychology with rotations at the Outpatient Clinic, Substance Abuse Residential Treatment Program, and the National Center for Post-Traumatic Stress Disorder - Behavioral Sciences Division. In 2005, Dr. Tull joined the Center for Addictions, Personality, and Emotion Research at the University of Maryland (College Park) as Director of its Emotion Division. From 2006 to 2008, he served as a Research Assistant Professor in the Department of Psychology at the University of Maryland. In 2008, Dr. Tull joined the Department of Psychiatry and Human Behavior at the University of Mississippi Medical Center, where he currently holds the positions of Associate Professor and Director of Anxiety Disorders Research. Dr. Tull is the 2009 recipient of the International Society for Traumatic Stress Studies Chaim and Bela Danieli Young Professional Award and the 2010 recipient of the Association for Behavioral and Cognitive Therapies President's New Researcher Award.
Dr. Tull's research focuses on emotion regulation within the anxiety disorders, with a particular focus on PTSD. His research examines the ways in which: (a) emotion regulation strategies that function to avoid emotion (and internal experience in general) may serve as a vulnerability factor for the development and maintenance of posttraumatic symptoms; and (b) emotional approach and acceptance (such as through mindfulness) may serve as a protective factor for anxiety disorder-related pathology. This research stems from a growing body of theoretical and empirical literature that suggests a paradoxical effect of emotional avoidance/control and, conversely, the potential benefits of accepting and being mindful of one's internal experience. Currently, Dr. Tull is investigating specific behaviors associated with emotion dysregulation and avoidance (e.g., substance use, risky sexual behavior) and their association with negative clinical outcomes (e.g., residential substance abuse treatment drop-out, HIV infection) among substance users with PTSD.
