Dr. Greenberg has helped to advance the fields of pulmonary and sleep medicine as an investigator in multiple research trials that have made contributions to our understanding of the pathophysiology and cardiovascular consequences of sleep disordered breathing. In addition, Dr. Greenberg was a co-investigator in a major international clinical trial that established the efficacy of continuous positive airway pressure therapy as an important treatment for patients with milder forms of obstructive sleep apnea. His work has also contributed to the development of new therapies for insomnia.
