Poultry Diagnostic and Research Center
Assistant Professor

Dr Carnaccini obtained her DVM degree from the University of Bologna, Italy in 2012 and her PhD in Comparative Biomedical Sciences from the University of Georgia in 2020. Her PhD research focused on studying the molecular determinants of antigenicity of the H9 subtype of avian influenza virus. She also contributed to study pathobiology and transmission of various influenza A virus subtypes in vitro and in vivo. Dr Carnaccini is specialized in both poultry medicine and general pathology as a diplomate of the American College of Poultry Veterinarians and the American College of Veterinary Patologists, respectively. She is now an Assistant Professor at the Poultry Diagnostic and Research Center, Population Health Department of the University of Georgia. Her appointment includes routine diagnostic for poultry species, teaching veterinary students, graduate students and residents, and development of her own independent research program. Carnaccini’s research, currently focuses on avian influenza pathobiology, evolution at the level of the wildlife-poultry interface. Ongoing collaborations include testing of antivirals against SARS-CoV-2 and study the pathology and tissue tropism of SARS-CoV-2 in multiple animal models.
