A committed academician and researcher, Dr. Stull has contributed extensive professional and academic service to his field and the university. He serves as associate editor of the Journal of Biological Chemistry and is a member of the Board of Directors for FASEB. Since his arrival at UT Southwestern, Dr. Stull has served as a member or chair of more than thirty committees in the graduate, medical or allied health schools. He is the holder of the Fouad A. Bashour Distinguished Chair in Physiology since 1992.
Dr. Stull?s research involves the cellular and molecular basis of how contraction of muscle cells occurs in response to chemical signals from nerves and hormones. Smooth muscle cells line the hollow organs of the body and are necessary for many functions, including movement of blood through arteries and veins, airflow in lungs, and propulsion of food through the gastrointestinal system. Skeletal muscles are essential for body movement and breathing while the heart pumps blood. In his current research integrating molecular genetic, biophysical, biochemical and physiological approaches, Dr. Stull is focused on signaling pathways that affect phosphorylation of the molecular motor myosin and hence, contractile performance in these different muscles.
