Applied poultry research focusing on emergency poultry disease response (e.g. avian influenza) emphasizing the 3Ds: depopulation, disposal and decontamination. Additional research involves the use of new lighting technologies to improve poultry production and sustainability while reducing energy costs.


Poultry health issues focusing primarily on poultry disease outbreak response, management and regionalization. Collaborates with USDA International Services, International Technical & Regulatory Capacity Building to provide two annual programs for international veterinarians and poultry professionals; Emergency Poultry Disease Response Certificate Program and the Poultry Disease Outbreak Management and Regionalization.
