Joel’s research program includes two main areas: (1) insect toxicology and (2) environmental toxicology and environmental chemistry of agrochemicals. His research in the insect toxicology area is focused primarily on natural products as insecticides and insect repellents, including investigations of their spectrum of activity, mechanisms of action, metabolism, synthesis of biorational derivatives and analogs, and quantitative structure-activity relationships. His scientific publications include 10 books, 7 review articles, 41 book chapters, and 142 peer-reviewed journal articles, and he holds 9 patents. He teaches in five graduate courses: Insecticide Toxicology, Pesticides in the Environment, Special Topics in Insect Toxicology, and portions of Principles of Toxicology, and Laboratory Methods in Toxicology. Joel has served as major professor for 44 graduate students who graduated from his lab, plus 3 current ones, and served as advisor for 13 postdocs.
