Viral Pathogenesis

We are studying the viral pathogenesis of alphaherpesviruses, a subfamily of the Herpesviridae. These viruses can cause severe illness in a wide variety of avian and mammalian species, including humans, and are known to establish latent infection in their host. Our overall goal is to develop virus-natural host models, in vitro as well as in vivo, to gain more insights into the underlying mechanisms of herpesvirus infections and reactivation.
