Dr. Cohen's areas of interest encompass health services research related to voice and swallowing disorders. Dr. Cohen enjoys studying the real world practice patterns involved in the evaluation and management of patients with voice and swallowing disorders and the relationship between practice patterns and the outcomes of patients with these varied conditions. 

Harrison N. Jones, PhD

harrison n jones

Harrison Jones, PhD, is an Associate Professor in the Department of Head and Neck Surgery & Communication Sciences at Duke University. Dr. Jones’ research interests include the use of exercise-based, behavioral treatments in individuals with neuromuscular conditions. For example, he is systematically investigating the effects of respiratory muscle training (RMT) on inspiratory and expiratory weakness in patients with late-onset Pompe disease (LOPD). He and his collaborators were also among the first to identify the presence of tongue muscle weakness in LOPD and he is currently investigating the diagnostic utility of measures of lingual function and structure in the differential diagnosis of this condition. His research is funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) and the Genzyme Corporation, and he has two U.S. patent applications for RMT-related technologies that are in further development in collaboration with industry partners.
