Major Research Interests: Virus cell interactions, pathogenesis of oncogenic EBV
Long standing research interests are in virus cell interactions and virus pathogenesis, particularly in the biology of Epstein-Barr virus (EBV). EBV is an oncogenic human herpesvirus that establishes persistent infections in almost 100% of the world's population. Most people are infected subclinically in childhood. However, the virus also causes infectious mononucleosis, oral hairy leukoplakia and immunoblastic lymphoma and is strongly implicated in the development of Burkitt's lymphoma, nasopharyngeal carcinoma, gastric carcinoma and Hodgkin's Disease. EBV has two major cellular targets, B lymphocytes and epithelial cells. Our long term goal is to understand how the virus enters and exits these target cells and how it spreads within and between its human hosts. Studies focus on the functions of the envelope glycoproteins critical to these processes and on the cellular proteins with which they interact.
