Adjunct Professor of Environmental Health

View Dr. Kadry's CV.

SPH Building, 4200 Valley Drive, Rm 2234T

Dr. Kadry is an adjunct professor at the University of Maryland's School of Public Health in College Park, MD. Previously, Dr. Kadry worked as a senior science advisor at the US Environmental Protection Agency's Center for Computational Toxicology and Exposure (CCTE) and the National Center for Environmental Assessment (NCEA) (retired, 2021).

Dr. Kadry has over 35 years of experience in toxicology and risk assessment, including academic research, drug safety and efficacy, food safety and environmental risk assessment. He worked as a consultant for the World Health Organization for five years. In addition, he was a member of the USA Codex Alimentarius team. As the Director of the EPA's Integrated Risk Information System (IRIS), he led the EPA's risk assessment development activities. He was the Chief of the Technical Analysis and Evaluation Branch, Risk Assessment Division, Office of Public Health Sciences, Food Safety and Inspection Service at the United States Department of Agriculture (USDA) before joining the EPA in 2006. 

Dr. Kadry has authored numerous peer-reviewed journal articles and book chapters. He has taught toxicological research and risk assessment principles and applications to a large number of graduate students, postdoctoral fellows and other professionals in the United States and other countries. Dr. Kadry worked with Dr. M. Haider (UMD) and two Egyptian professors to create an international global graduate course on the use of risk assessment to ensure food safety and security (MIEH 607). This is a web-based course that is very popular at both the University of Maryland and Cairo University.

Dr. Kadry is very involved in the community service in the tri-state area (DC, MD and VA). He works for the Federal Mediation and Conciliation Services (FMCS) as a certified lead mediator. He was able to successfully mediate many cases, including workplace disputes, scientific disagreements and EEO complaints. He assisted the disputing parties in reaching mutually acceptable resolutions. He is also a green belt certified Lean and Six Sigma professional. He taught a large number of federal employees and others how to use the lean management system to improve the efficiency and quality of various work processes. Mediation and a lean management system, he believes, are good complementary tools to aid in the risk assessment procedure.

Dr. Kadry earned his Doctor of Veterinary Medicine from Cairo University in Egypt, as well as his MS and PhD in toxicology from Zagazig University in Egypt. Dr. Kadry is a member of the Society of Toxicology (SOT), Society of Risk Analysis (SRA), International Association for Food Protection (IAFP), and other professional organizations and is certified by both the American Board of Toxicology and the National Board of Veterinary Medicine. He is a past president of SOT's Toxicologists of African Origin (TAO) and a member of the African Chapter of SRA's Board of Directors. He is also a former president of the Association of Government Toxicologists.
