Daniel M. Stout II

Title: Biological Scientist

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Exposure Measurements and Analysis Branch

Daniel’s research focuses on the behavior of pesticides, primarily insecticides, following their application in the residential environment and the development of measurement tools to determine the potential for human exposures. Emphasis is placed on advancing both measurement technology and analytical methodology to understand residential fate and transport issues as they relate to exposure and minimizing potential risks. In addition, Daniel’s work has contributed towards the national bed bug epidemic and associated misuse of pesticides in the residential environment as well as promoting the principal of pesticides safety and integrated pest management.
