Microbiology Departmental Seminar
Leon Johnson Hall, Room 346
Dr. Johnson is currently the Director of the Toxicology Portfolio at the Army Institute for Public Health where he has specialized on the toxicity of military unique compounds and development and evaluation of sensitive indicators of stress (e.g., immunotoxicity) for use in field applications and toxicity testing. He has extensive experience in risk assessment and has developed and tested new methods in improving exposure/effects relationships. Current work involves the development of a phased approach to the gathering toxicity data for new compounds. Other work has included the development of a process to derive toxicity reference values for terrestrial wildlife and the development of a process to assess risk via inhalation exposures in non-combat deployed personnel. He has authored over 50 peer-reviewed publications, book chapters, and technical reports.
Dr. Johnson is the Chair of the Tri-Service Toxicology Consortium (TSTC), steering committee chair of the Joint Army-Navy-NASA-Air Force (JANNAF) Propulsion Committee, Subcommittee on Safety and Environmental Protection, the chair of the terrestrial toxicity subcommittee of the Biological Fate and Effects Committee of the American Society for Testing and Materials (ASTM), and the vice-chair of Ecological Risk Assessment Advisory Group for the Society of Environmental Toxicology and Chemistry. He is a member of the Board of Directors of the American Board of Toxicology.
