Basic research

Dr. Parcells studies the function of genes encoded by Marek’s Disease Virus (MDV), a T-lymphoma-inducing herpesvirus of chickens.  The projects in his laboratory range from the functional interactions of viral and cellular proteins as they relate to MDV infection and pathogenesis, the evolution of MDV virulence, to the development and testing of vaccines for Marek’s disease. Dr. Parcells has a strong interest in tumor immunology and tumor virology and vaccine development. Dr. Parcells has a strong interest in tumor immunology and tumor virology and has a current project developing an anti-tumor vaccine for canine hemangiosarcoma.

Industry-supported research

Dr. Parcells works with Poultry and Animal Health Companies to develop and test new vaccines, perform basic mechanism of action studies, and provide expertise in product development and testing.
