Dr. Steven P Bradbury

In August of 2015 Dr. Bradbury was appointed as a professor of environmental toxicology in the Departments of Natural Resource Ecology and Management and Entomology.  He is also a faculty member in ISU's Toxicology and Ecology and Evolutionary Biology Programs.  From July 2014 through July 2015, Steve served as a visiting professor in ISU's Department of Entomology. 

Dr. Bradbury is contributing to research and extension in University-wide toxicology, environmental, agriculture and natural resource science and policy programs. Areas of emphasis include pesticide resistance management, pollination services, monarch butterfly conservation and sustainable agriculture, including the role of integrated pest management within nested layers of governance. Steve's areas of teaching include toxicology, pesticide and chemical risk assessment and related policy topics.

Steve retired from the U.S. Environmental Protection Agency in 2014.  During his last 4 years in EPA he directed the Agency’s Office of Pesticide Programs (OPP).  As a senior executive in OPP, Steve led the evaluation of new and existing pesticides, including biotechnology products, and the integration of Federal pesticide registrations within national, state and stakeholder-initiated programs addressing emerging, high impact pests; pesticide resistance; and water quality, endangered species and pollinator protection. Prior to joining OPP in 2002, Steve had over 15 years of experience in EPA’s Office of Research and Development leading research to advance human health and ecological risk assessments in support of water quality, pesticide and industrial chemical programs. 

Steve 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).  He has published over 75 peer-reviewed journal articles and book chapters and has an extensive record of invited presentations at international and national scientific conferences. 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.

On December 15th, 2020 the U.S. Fish and Wildlife Service announced that the monarch butterfly is warranted for listing under the Endangered Species Act (ESA).  However, because of on-going work with higher-priority species, the Service precluded issuing an immediate proposed listing rule.
