STEVEN P. BRADBURY, PhD


Steven P. Bradbury, PhD, was formerly the Director of the U.S. Environmental Protection Agency’s Office of Pesticide Programs (OPP) and retired from the Agency after 12 years of senior executive service leading Federal pesticide risk assessments and regulatory determinations under the Pesticide Registration Improvement Act, Federal Insecticide Fungicide and Rodenticide Act, Federal Food Drug and Cosmetic Act and the Food Quality Protection Act.  Prior to joining OPP, Dr. Bradbury had over 15 years of experience in EPA’s Office of Research and Development (ORD) leading research to advance human health and ecological risk assessments in support of the Clean Water Act, Comprehensive Environmental Response Compensation and Liability Act, FIFRA and the Toxic Substance Control Act.  

As the Director of OPP he was responsible for managing an Office with an annual budget of $150 million and leading a staff of 750 scientists and risk managers, including 11 senior executives.  He led the evaluation and regulation of new and existing pesticides, including nanoscale and emerging biotechnology products.  He also led initiatives to integrate pesticide risk assessment and regulation with broader agriculture and natural resource initiatives addressing emerging, high impact pests; pesticide resistance; and water quality, endangered species and pollinator protection programs.   Advancing and implementing practical, science-based solutions to complex pest management, pesticide stewardship, and human health and environmental protection challenges was fostered by his ability to forge collaborations across numerous Federal, State, and international agencies and a wide array of parties, including industry, growers, pesticide applicators, public health officials, environmental organizations and animal welfare groups.  

As a senior executive in the Office of Pesticide Programs, he:

  • Provided overall leadership and management for implementing the nation’s pesticide regulations in coordination with other Federal statutes
  • Completed the re-registration program
  • Launched the registration review program and PRIA
  • Initiated 21st Century human health and ecological testing and assessment methods for pesticides
  • Established the National Academy of Science-reviewed risk assessment methods for threatened and endangered species
  • Advanced Integrated Pest Management and pesticide stewardship programs
  • Implemented the risk-based endocrine disrupter screening program for pesticides 
  • Furthered harmonized  international scientific and regulatory positions

Dr. Bradbury started his EPA career in 1985 as a research toxicologist in ORD leading scientific advances to support TSCA, FIFRA, CWA, and CERCLA programs.  He subsequently moved into management and joined the senior executive service in 1999 and served for 3 years as the Director of the Mid-Continent Ecology Laboratory in Duluth MN.  As the Laboratory Director he led national programs investigating the effects of chemical and non-chemical stressors on freshwater ecological resources.   He then joined OPP and served as the Director of the Environmental Fate and Effects Division, Director of the Special Review and Re-registration Division, Deputy Office Director for Programs and then the Office Director for 4 years.

As a senior executive in the Office of Research and Development, he:

  • Implemented monitoring and assessment programs for small watersheds and the Great Lakes and Great Rivers basins 
  • Co-established EPA’s 21st Century computational toxicology program
  • Led advances in ecological risk assessment methods for chemicals and pesticides

Dr. Bradbury has a BS in Molecular Biology (University of Wisconsin-Madison) and a MS in Entomology (Insecticide Toxicology) and a PhD in Toxicology and Entomology (Iowa State University).  In 2014, Dr. Bradbury received the Henry A. Wallace Award for Outstanding Leadership to National and International Agriculture from the College of Agriculture and Life Sciences, Iowa State University.

Dr. Bradbury also holds a professorship at Iowa State University in the Departments of Natural Resource Ecology and Management and Entomology, where he contributes to teaching, research and extension in University-wide toxicology, environmental, agriculture and natural resource science and policy programs.  Dr. Bradbury is a member of the American Association for the Advancement of Science, American Chemical Society, Entomological Society of America, Society of Environmental Toxicology and Chemistry, and the Society of Toxicology.

Dr. Bradbury has published over 70 peer-reviewed journal articles and book chapters and has an extensive record of invited presentations at international and national scientific conferences.  He has in-depth and diverse experiences in assessing and managing the use of pesticides, chemicals, and biotechnology products in urban, suburban and rural settings.  Dr. Bradbury has broad international experience working with the Organization of Economic Cooperation and Development, the North American Free Trade Agreement, the European Food Safety Authority, as well as Canadian; Mexican; Australian; Chinese; European Union, and EU member state, pesticide regulatory authorities through bilateral and multi-lateral agreements.
