Dr. Bill Morgan is Director of Radiation Biology and Biophysics in the Biological Sciences Division. In this role, he provides scientific leadership at PNNL in the area of effects of radiation exposure to human health. Morgan is a leading researcher in the field of radiation biology and the long-term biological effects of radiation exposure. He is the Principal Investigator for the U.S. Department of Energy's Low Dose Radiation Research Program Scientific Focus Area at PNNL.
Dr. Morgan joined PNNL in 2008. Before then, he was Professor and Director of the Radiation Oncology Research Laboratory at the University of Maryland, Baltimore, as well as an Affiliate Scientist at PNNL. Before joining the University of Maryland in 1999, Morgan led radiation research laboratories at the University of California, San Francisco, and Lawrence Berkeley National Laboratory. He is a scientific representative for regulatory agencies such as the United Nations Scientific Committee on the Effects of Atomic Radiation, the International Commission on Radiological Protection, and the National Council for Radiation Protection.
