  • Research Interest

    The focus on my laboratory is the manipulation of the immune response by a virus that allows that virus to grow more effectively within a host, despite the very immune system it is manipulating. In the past, a major focus of research was how viruses “hid” from the immune system. Now, we understand that the viruses have evolved to hijack key signaling components of immune cells to produce a microenvironment that allows the viruses to better persist and replicate inside the host. Our laboratory is currently focused on three different projects: (1) how HIV infects different cell types to allow for better spread and persistence by manipulating the cytokines produces, (2) determination of the mechanisms by which the oncogenic herpesvirus KSHV is able to manipulate the activation of innate cytokines and T cells with specialized viral proteins, and (3) understanding why SARS-CoV-2 is able to both induce and diminish innate immune protein production to enhance its replication within cells. Taken together, our laboratory is focused on better defining how viruses manipulate components of the immune system so that we can better understand how to limit disease and control viruses.
