Service on National Study Sections

Reviewer for Biodefense Vaccine Enhancement BAA NIH-BARDA-NIAID-DMID-AI2007007. Review of contract proposals received in response to the Broad Agency Announcement (BAA) that addresses third generation anthrax vaccines as well as other category A and B pathogen vaccines. This is an important initiative since eventually these products will likely be considered for the National Stockpile.

Convener for the Workshop session titled “Vaccines & Vectors III.” American Society for Virology Annual Meeting 2008, Ithaca, NY

Session Chair (neurovirology) for the 19th annual virology meeting (German Society for Virology), 2009, Leipzig, Germany.

Research Interests

Areas of research: Molecular biology, viral pathogenesis, vaccine/antivirals, and diagnostics development.

The research in my laboratory has focused on viral pathogenesis, vaccine development and on development of animal models to test new vaccine candidates and antiviral drugs. My main research interest is in understanding the mechanisms by which emerging RNA viruses cause encephalitis, hemorrhagic fever, or respiratory diseases. Central nervous system (CNS) invasion by RNA viruses is particularly a complex and fascinating process. We seek to elucidate the nature of the neuroinflammatory response to CNS invasion by viruses in diverse families such as Togaviridae, Orthomyxoviridae, Bunyaviridae and Arenaviridae. Our approach is designed to provide expertise for the development and evaluation of vaccines and anti-viral drugs in collaboration with partners in academia (within and between institutions), in biotechnology, and in federal agencies
