Dr. Steven L. Simon is a radiation physicist and part of the Dosimetry Unit of the Radiation Epidemiology Branch (REB), which provides dose estimation in support of Branch epidemiologic studies and develops exposure assessment methods to improve the science of dosimetry. Dr. Simon received a B.S. in physics from the University of Texas, an M.S. in radiological physics from the University of Texas Health Sciences Center in Dallas, and a Ph.D. in radiological health sciences from Colorado State University. Previously, he was on the research faculty at the University of Utah, the academic faculty at the University of North Carolina-Chapel Hill, was a medical physicist for the University of New Mexico at Los Alamos National Laboratory, a senior staff officer at the National Research Council, and director of the Marshall Islands Nationwide Radiological Study. He joined the NCI in 2000. Dr. Simon has received NIH Merit Awards in 2004, 2009, 2011, and 2014 for his research in applications in radiation dosimetry to epidemiological research. In 2010, he received the Division of Cancer Epidemiology and Genetics Exemplary Service Award for his deployment to the U.S. Embassy in Tokyo during the Fukushima nuclear crisis, where he served as a DHHS technical expert in radiation dose and risk. Dr. Simon has been a member of the National Council on Radiation Protection and Measurements for more than 12 years and is currently a Scientific Vice President and Chair of the NCRP’s Program Area on Radiation Measurements and Dosimetry. He has been an Associate Editor of Health Physics for 24 continuous years.
