Research Interests

Using herpesvirus reactivation as a model to study gene regulation

Epigenetic gene regulation by using herpesvirus reactivation as a model system. Epigenetic components of chromatin, including host and viral factors that interact to facilitate both the establishment and maintainance of the chromatin state as well as the molecular transitions that take place during reactivation (“chromatin remodeling”). Post-translational modifications that are imparted on critical viral and host factors are also an area of research in our lab.
