Dr. David Ashley is a Research Professor in the School of Public Health at Georgia State University. He was appointed to this position in August 2017. Before that, he spent 33 years in the United States Public Health Service, retiring in 2016 at the rank of Assistant Surgeon General/Rear Admiral-Lower Half.
He was at the Environmental Health Laboratory of the Centers for Disease Control and Prevention’s National Center for Environmental Health from 1983 until 2010. Starting in June 2010 he was the inaugural director of the Office of Science of the Food and Drug Administration’s Center for Tobacco Products (FDA/CTP). In this role, he was instrumental in carrying out the regulatory authorities of the 2009 law which gave FDA authority to regulate tobacco products; this law requires that FDA base its decisions on science, including proposals to reduce the harm caused to those who smoke and to discourage youngsters from smoking. FDA CTP’s Office of Science is responsible for identifying, developing, and enhancing the science related to tobacco products, their use, and the resulting morbidity and mortality so that regulatory decisions will have the greatest impact on improving public health. To accomplish this goal, they provide the scientific support for regulations and guidance, review tobacco product applications, evaluate the knowledge basis for regulatory decisions, and carry out research to fill the gaps in scientific knowledge related to tobacco product regulation.
Dr. Ashley has performed extensive research related to the impact of cigarette design and contents on the emissions from tobacco products, how people use tobacco products, and resulting biomarkers of exposure. He has published over 140 peer-reviewed articles and book chapters related to biophysics, environmental chemicals, biomarkers of exposure and the constituents of tobacco and tobacco smoke. He was a contributing author for the recent Surgeon General’s Report entitled How Tobacco Causes Disease—The Biology and Behavioral Basis for Tobacco-Attributable Disease and has presented extensively at scientific meetings on the chemistry of tobacco and tobacco smoke and biomarkers of exposure. He serves on the World Health Organization (WHO) Study Group for Tobacco Product Regulation and was the Chair of the WHO Tobacco Laboratory Network from 2006 until 2010.
