Dr. Jiang has a solid background in science with over 20 years of experience in research, teaching and services. He has been principal and co-principal investigator on grants and contracts totaling over $8 million. He has published and presented over 50 papers and presentations in the areas of chemistry, food safety, environmental contamination and pest management. Dr. Jiang co-authored over 100 IR-4 Analytical Summary Reports that have been submitted to the Environmental Protection Agency (EPA) for pesticide registration. While being on the United States Department of Agriculture (USDA) Foreign Agricultural Service’s mission, Capacity Building, Dr. Jiang and colleagues travelled to many countries in Asia, Africa and Central and South America to help these developing countries develop internationally recognized pest management programs and to establish their regulatory systems, which are very important to global food safety. He worked in industries in Toronto and Detroit before joining Michigan State University (MSU) in 2003. Dr. Jiang became a faculty member at the Department of Entomology in 2006. Dr. Jiang is serving as a senior editor of the Bulletin of Environmental Contamination and Toxicology.

For more than 50 years, the USDA Interregional Research Project Number 4 (IR-4 Project) has been the primary resource in the United States for facilitating registrations of pesticides on specialty crops and minor uses, which include the majority of fruit, vegetable and ornamental crops. The IR-4 program is fully funded by the USDA. The IR-4 Project contributes more than $7.3 billion to annual gross domestic product (GDP) in the U.S. Therefore, IR-4 is very important to U.S. specialty crop growers, and in particular to growers in Michigan, which has one of the most diverse agricultures in the U.S.
Overall, my work with IR-4 at MSU is providing the reliable and high quality residue data necessary for tolerance establishment with the EPA. All of these studies are conducted under the demanding regulations of the EPA’s Good Laboratory Practice (GLP) system. As can be seen from my CV, I have authored over 100 Analytical Summary Reports submitted to the EPA. For example, mainly based on our many years’ work at MSU, the EPA established in 2012 a number of tolerances for residues of an insecticide, Bifenthrin, in vegetables, fruits, sweet corn, nuts, tea, grasses and other crops, totaling 56 food crops and crop fractions, which allows their legal use in the U.S. (40 CFR 180.442, Sept. 4, 2012). In many cases, without the IR-4 program such crops could not be grown economically.
Recently, I have become active in the capacity building program of the USDA Foreign Agricultural Service that helps developing countries improve their agricultural systems (such as minor use programs and regulatory systems) and enhance their international trade capacities. Many institutions in the U.S. participate in the capacity building program. I have been actively participating in the capacity building program for four years. My involvement in the capacity building program is to provide the services for the pesticide laboratory GLP training. One of my roles is the laboratory trainer for method validation. For example, I have been the main trainer to the laboratory trainings for capacity building program studies in some of the Association of Southeast Asian Nations countires (Malaysia, Singapore, Thailand, Philippines, Indonesia, Vietnam) and Central and South America. Recently, we started capacity building program projects in Africa (Egypt, Morocco, Ghana, Senegal, Uganda and Kenya). I have been working closely with China to be on the team to foster cooperation and information exchange with the intention of a reciprocal recognition of each other’s GLP programs and mutual acceptance of pesticide residue data.
