Research Summary

I joined Dr. Billiar’s research group as a postdoctoral associate in the Department of Surgery in the University of Pittsburgh in Nov, 2010. I started a research project investigating the cell-specific roles of Toll-like receptor 4 (TLR4) in sepsis. Our work showed cell-type specific roles for TLR4 on myeloid cells and hepatocytes to regulate bacterial/LPS clearance and systemic inflammation during sepsis. My long term research interests involve assessing innate immune responses and the mechanisms that lead to immune dysregulation following sepsis injury.
