William F. Morgan, Ph.D., D.Sc.


William Morgan
William F. Morgan

Dr. William F. Morgan is the Director of Radiation Biology and Biophysics in the Biological Sciences Division at the Pacific Northwest National Laboratory (PNNL) in Richland, WA. Dr. Morgan joined the staff at PNNL in August 2008 to lead the systems radiation biology initiative. His research has focused on the long-term effects of exposure to low doses of ionizing radiation, specifically the molecular, biochemical, cytogenetic, cellular and tissue responses to low doses of radiation and how these might translate into potential cancer risks.
