Biography

My research interests are in the assembly and transmission of virus particles. I am particularly interested in the molecular mechanisms that occur in order for influenza to assemble an infectious virus particle and for that particle to transmitted from one host to another. My previous work focused on the role of the cytoplasmic tail of the influenza M2 protein in the incorporation of the internal virus components. I have identified individual amino acids in the M2 cytoplasmic tail that are critical for that function, and future work will focus on identifying why those residues are critical. More recently, I have worked as part of a multidisciplinary team to capture and quantify influenza virus particles from infected human volunteers during an epidemic. In future work in this area, I would like to apply this technology to animal models of influenza (or other viruses) to begin to identify the molecular determinants of influenza aerosol generation.

I am also involved in an interdisciplinary effort to identify biomarkers that might be carried by a person who seeks to develop an influenza-base bioweapon. My role in this effort is to try to identify immune and microbiome signatures that are representative of someone who is engaged in influenza gain-of-function research.
