Dr. Gabriel G. Haddad is physician-in-chief and chief scientific officer at Rady Children's Hospital-San Diego and chairman of the Department of Pediatrics at UC San Diego School of Medicine. A leading specialist in pediatric respiratory medicine, he is also an accomplished physician-scientist.

Receiving his medical education and initial medical training at the American University of Beirut in Lebanon, Dr. Haddad went on to complete additional training at the University of Texas in Houston, followed by a fellowship at Columbia University in New York, where he joined the faculty in 1978. A decade later, he accepted an appointment at Yale to direct the Respiratory Medicine Section and serve as chief of clinical service in respiratory medicine. Shortly thereafter, he became a professor of cellular & molecular physiology. In 2002, he was appointed chairman of the Department of Pediatrics at Albert Einstein College of Medicine in New York and also pediatrician-in-chief at The Children's Hospital at Montefiore Hospital.

Dr. Haddad is passionate about developing better care through research. In recent years, his research has focused on the basis for cell and tissue injury at the molecular level when tissues and organs are deprived of nutrients and oxygen.

Dr. Haddad has published more than 230 articles and manuscripts, written more than 100 chapters, and authored numerous medical texts including the landmark "Basic Mechanisms of Pediatric Respiratory Disease." He sits on numerous national committees, including those of the National Heart, Lung and Blood Institute and March of Dimes, and is a member of 18 distinguished medical societies, many in a leadership role.

Additionally, Dr. Haddad has held numerous editorial appointments, is a reviewer for 29 respected medical journals and is the recipient of numerous awards and honors, including election into the Association of American Physicians. He has been invited to speak at more than 160 national and international conferences and is also a member of the St. Jude Children's Research Hospital Board of Governors.

Dr. Haddad is married and the father of three children, a daughter and two sons.
