Regulatory (US EPA) and basic research in developing analytical methodologies for the determination of pesticide residues in fruits and vegetables.
Provide growers with new chemical tools to address emerging pests by contributing to research studies which result in new uses on pesticide registration labels.
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.
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.
