Thomas T Wixson    Chemist /ARSUserFiles/20920500/Todd/IR4.jpg  **Research Interests:** Regulatory (US EPA) and basic research in developing analytical methodologies for the determination of pesticide residues in fruits and vegetables. **Aims:** Provide growers with new chemical tools to address emerging pests by contributing to research studies which result in new uses on pesticide registration labels. **Background:** I began my analytical chemistry career in a veterinary toxicology laboratory.  After moving to USDA, I worked on the plant/chemical/insect interactions in a chemical ecology lab.  I later transitioned to the IR-4 program and have been working on plant residues for over 20 years. **Approach:** The IR-4 laboratory employs state of the art analytical equipment to detect chemical residues in fruits and vegetables.  Instrumentation includes, but is not limited to: gas chromatography, liquid chromatography, and mass spectrometry. **Laboratory Personnel:** Anne Kenny Chapman, Biological Science Technician Song Jarman, Physical Science Technician Faradeh Rehfield, Agricultural Science Technician
