My research interests are viral diseases of animals, with an emphasis on emerging zoonotic viral infections. My current research focuses on understanding mechanisms of pathogenesis and developing vaccines for different zoonotic viral pathogens, such as Influenza virus, Rift Valley Fever virus and other viral infections in livestock and poultry. I am also interested in development of rapid detection systems for viral diseases.


My primary teaching role is to further develop graduate student training in virology. I participate in the teaching of one graduate course (DMP-910, Pathogenic Mechanisms of viruses, 3 credits) with other faculty.
