I have been working within the areas of innate immunity and signal transduction beginning as a graduate student in the laboratory of Dr. Glen Barber at Emory University, where I began intensive research on the innate immunologic response to RNA virus infection. In particular, I worked extensively on the area of virus type I Interferon induction, and I was able to demonstrate interactions between interferon induced genes and the host protein synthesis machinery.
I next expanded my knowledge in innate immunity by pursuing training with Dr. Stefanie Vogel at the University of Maryland Baltimore (UMB). My work with Dr. Vogel has focused on Toll-Like Receptor (TLR) biology, and specifically, how bacteria are able to govern type I interferon production through various TLRs.
My current research focus involves investigation into the immunomodulatory effects of type I interferons in bacterial pathogenesis, and specifically how interferon can be immunosuppressive during Salmonella Typhimurium oral infections.
