Current Research
The first major focus of my research is to understand host responses to infection by bunyaviruses such as Rift Valley fever virus (RVFV), alphaviruses such as Venezuelan Equine Encephalitis Virus (VEEV) and human retroviruses such as HIV. Specifically, I am interested in deciphering the influences of specific phosphosignaling events occurring in infected host cells that correlate with viral replication and in utilizing such events that are crucial for pathogen replication to design novel therapeutic inhibitors. In addition to identifying novel therapeutic candidates, my research interest also extends to defining the mechanistic basis behind pathogen inhibition when using host-based therapeutics.
The second aspect of my research focus includes extracellular membranous vesicles called exosomes, specifically those produced by virally infected cells (Bunyaviruses, Alphaviruses, Human retroviruses). Exosomes from infected cells will differ significantly in a proteomic and genomic capacity from those produced by uninfected cells. Such information can be exploited to understand transfer for genetic and proteomic information to naïve cells (intercellular communication). Such information can also be utilized to discover novel disease/pathogen specific biomarkers, vaccine and therapeutic candidates.
