Dr. Buchweitz is interested in the analytical measurement of toxic chemicals in biological and environmental matrices of veterinary concern. His primary research interest is in the application of analytical techniques to animal death investigations to discern intentional from unintentional poisoning incidents. An additional research interest is in the area of dried blood spot analysis. Veterinarians and wildlife biologists have demonstrated a need to assess environmental contaminants, such as heavy metals, rare earth elements, and persistent organic pollutants in the blood of animal species too small for routine blood tests. The extension of elemental and organic compound detection to dried blood spots may prove to be a valuable tool in this endeavor.
