The author of over 110 peer-reviewed publications, Dr. Nardell is a prominent researcher of multidrug resistant tuberculosis (MDR-TB), with a particular focus on airborne TB transmission and control. He is currently studying the transmission of MDR-TB and the effectiveness of various control interventions in several research projects funded by the National Institute of Occupational Safety and Health. He is also involved in a 5-year Fogarty Innovation Grant that uses new technological approaches to airborne infection control to train architects, engineers and physicians in air disinfection research in Peru, South Africa, and other high-burden countries. He is actively developing more efficient and inexpensive ultraviolet germicidal irradiation fixtures and a new environmentally-safe chemical vapor that may reduce airborne transmission.

Dr. Nardell has served as president of both the Massachusetts Thoracic Society and the International Union Against Tuberculosis and Lung Disease (IUATLD), North American Region. He is also the incoming chair of the IUATLD Tuberculosis Section, Paris, and the recipient of the Chadwick Medal of the Massachusetts Thoracic Society.
