Research Summary

My lab focuses on the mechanisms of organ failure and coagulopathy following trauma and hemorrhage.  Specifically, we are interested in the role of innate immune activation in the regulation of hemostasis and thrombosis. We are particularly interested in platelet biology in sterile injury and sepsis.   In addition, I have a translational research interest in outcomes following massive transfusion and the clinical assessment of coagulation defects in trauma and sepsis.
