Research Interests

Our overall research interest is to study the mechanistic links between blood clotting, inflammation, and the host immune system. We integrate lab-based studies with clinical/translational projects to better understand why dysregulation of these pathways contributes to vascular disease states such as thrombosis and sepsis.



Our research focuses on three key areas:

1. Role of immune cells in the pathophysiology of thrombosis
2. Novel pre-clinical strategies for the treatment of sepsis
3. Precision medicine approach for the treatment of sepsis



We perform studies at the levels of cell biology, biochemistry, molecular biology, mouse models of sepsis, and human patients.
