    Research Interests

    Sepsis is a major public heath problem that can affect anyone at anytime. Patients that survive severe sepsis often display compromised innate and adaptive immunity. This immunosuppressive state is exhibited by susceptibility to ‘secondary’ infections with intracellular pathogens that are normally controlled by CD8 T cells. CD8 T cells play an important role in the control and elimination of intracellular pathogens. Thus, alterations in the naïve CD8 T cell repertoire can seriously compromise T cell immunity. Little is known about the long-term immune consequences for an individual that has survived sepsis. My current research focuses on understanding the long-term consequences of sepsis on CD8 T cell homeostasis and if this impacts the ability of CD8 T cells to respond to pathogenic challenge.
