Daniel Morgan, Ph.D., D.A.B.T., manages and participates in multidisciplinary teams of scientists from the National Toxicology Program (NTP) and the National Institute of Environmental Health Sciences that are working to develop research programs to address a broad array of toxicological study needs for chemicals selected for study by the NTP. This includes the design, analysis, interpretation, and integration of carcinogenicity, reproductive and developmental, genetic, and general toxicology studies. These research programs serve to identify hazards associated with chemical exposure and increase our understanding of the interaction between chemical exposure and the development of disease. Study results are published as NTP Technical Reports and peer-reviewed research papers in scientific journals and provide critical data for use in risk assessment for human exposure.

Morgan also serves as the NTP's senior discipline expert in respiratory toxicology. His research interests focus on the biochemical and molecular mechanisms of inhaled environmental toxicants. Before joining the Toxicology Branch, Morgan was group leader of the Respiratory Toxicology group in the NTP Laboratory, and Project Officer for the NIEHS inhalation facility. His research focused on mechanisms of pulmonary toxicity of NTP chemicals at the tissue, cellular, and molecular levels.

Morgan received a B.S. in microbiology and biology in 1975, and a Ph.D. in Pharmacology and Toxicology in 1982 from the University of Kansas. He completed postdoctoral training in toxicology at the Comprehensive Cancer Center, Duke University Medical Center. Morgan worked as assistant director of the Laboratory of Environmental Toxicology and Pharmacology at Duke, and project leader in the cellular and molecular toxicology laboratory at Northrop Services prior to joining the NTP in 1988.
