Research and Clinical Interests

The innate immune response provides the first line of defense against infection. We study the type I interferon (IFN) system, an essential component of innate immunity to viral infection, focusing on how cells recognize infectious organisms and induce IFN production, how they respond to secreted IFN to establish an antiviral state, and how these events are orchestrated at the molecular level using paramyxoviruses, herpesviruses, and poxviruses as model systems in gene-targeted mice.
