Division of Residue Chemistry
Dr. Linge (Emily) Li is a Research Chemist in the Office of Applied Science at FDA’s Center for Veterinary Medicine. She joined the Division of Residue Chemistry after working at the Division of Applied Veterinary Research for six years. She received her Ph.D in Analytical Chemistry from Loyola University Chicago. She joined FDA as a Research Chemist in 2017 after working at Contract Research Organizations for more than 12 years. Her primary responsibilities at CVM include conducting and coordinating research in analytical method development and validation using liquid chromatography and tandem mass spectrometry (LC-MS/MS) for veterinary drug pharmacokinetics, tissue depletion, bioequivalence study, residue analysis and regulatory bridging study in food-producing and companion animals.
- LC-MS/MS analytical method development and validation.
- Pharmacokinetics, tissue depletion, bioequivalence study, residue analysis and regulatory bridging study.
- Quantitation and confirmation analysis of veterinary drug residue in food-producing animal products.
