Dr. Morgan has more than 20 years of experience in operational health physics. As a graduate student he was licensed by the US Nuclear Regulatory Commission as a Senior Nuclear Reactor Operator for the TRIGA Reactor at University of California, Irvine. Trained as a radiation biologist, Dr. Morgan has conducted biomedical research in radiation biology, human cancer genetics, clinical radiation oncology and health physics. He has also taught Principles of Radiation Biology to radiation oncology residents and radiation therapy technologists in training.

In 1994 Dr. Morgan was appointed Radiation Safety Officer of a large community teaching hospital in Los Angeles. In 2000, he was hired as the Radiation Safety Officer of a company that manufactured and distributed radioactive source. In this position he was responsible for employee health and safety in a manufacturing operation that handled thousands of curies of radioactivity each year.

In 2003 Dr. Morgan moved to the University of Rochester where he was hired as the Radiation Safety officer for a research university and associated medical school and Level I trauma facility. In 2011 he was named Executive Director of Radiation Safety Programs and Chief Radiation Safety Officer for Columbia University, including Barnard College, NewYork Presbyterian and Allen Hospitals, New York State Psychiatric Institute, Lamont-Doherty Earth Observatory (Palisades, NY) and Nevis Laboratories (Irvington, NY).
