Biography

Dr. Gregory Tyson is the Director of the Veterinary Laboratory Investigation and Response Network (Vet-LIRN). He received his PhD in microbiology from Northwestern University and joined the FDA in 2014. For several years he performed research to support the National Antimicrobial Resistance Monitoring System (NARMS), which performs One Health antimicrobial resistance surveillance of foodborne pathogens. He joined Vet-LIRN in 2021. Vet-LIRN comprises a network of 46 veterinary diagnostic laboratories that support various efforts within CVM, including performing non-regulatory testing of food or animal samples in response to consumer complaints about CVM-regulated products.

Research

Vet-LIRN’s work focuses in several areas, including

  • Responding to consumer complaints received by CVM’s Office of Surveillance and Compliance, including non-regulatory testing conducted by Vet-LIRN laboratories
  • Development and evaluation of methods by Vet-LIRN laboratories to detect potential issues in CVM-regulated products, with a focus on animal foods
  • Conducting antimicrobial resistance monitoring of foodborne and zoonotic pathogens in animals, using this information as part of One Health AMR monitoring
  • Supporting the COVID-19 pandemic response, including the development and expansion of methods for testing in animals
