    Research Interests:

    - Molecular Virology of HIV and Influenza
    Our laboratory's research is focused mainly on the structure and assembly of the human immunodeficiency virus (HIV) and influenza A virus, with the goal of developing new approaches to antiviral therapy. We are particularly interested in understanding how each of these viruses is able to recognize and package its genomic RNA into new viral particles as they form within an infected cell. By combining three-dimensional structural analysis with targeted mutagenesis of virally encoded macromolecules, we are elucidating specific RNA-RNA and RNA-protein interactions that are critical for replication, and that may offer new targets for antiviral drugs.

    My other scientific interests extend broadly over the fields of immunology, virology, and the molecular basis of human disease. Past projects have included studies of human telomerase RNA; of the apoptotic regulatory proteins Bcl2 and Bax; and of immune responses to multicellular parasites; as well as co-discovery of a novel form of human severe combined immunodeficiency (SCID) that results from an inherited defect in ZAP-70, a tyrosine kinase involved in T-cell receptor signaling. In addition, as a pathologist, I have enjoyed several opportunities to collaborate in characterizing novel transgenic or knockout mouse strains whose phenotypes shed light on important facets of mammalian development, immunity, and carcinogenesis.
