John P. Buchweitz

Dr. John P. Buchweitz serves as Associate Professor and Toxicology Section Chief at the Michigan State University College of Veterinary Medicine's Veterinary Diagnostic Laboratory. His research focuses on analytical toxicology applications for veterinary death investigations and dried blood spot methodology for environmental contaminant detection in small animals.

• B.S. Biochemistry (1992)
• M.S. Animal Science (2001)
• Ph.D. Pharmacology & Toxicology (2007)
• Postdoctoral Fellowship at Van Andel Research Institute

Key research areas include:

• Chemical exposure differentiation (intentional vs. accidental)
• Environmental metal analysis in veterinary species
• Dried blood spot diagnostic techniques
• Companion animal sentinel monitoring

His publications span veterinary toxicology, environmental health, and comparative pathology, with recent emphasis on liver disease mechanisms and environmental contaminant detection. Dr. Buchweitz collaborates with the Gastrointestinal Stress Biology Laboratory and maintains active research in hepatobiliary toxicology and metabolic syndrome.
