Description of Research Expertise:

Dr. Reilly conducts translational patient-oriented research in critical care medicine aimed at understanding clinical and molecular risk factors for sepsis and the acute respiratory distress syndrome (ARDS). He collaborates with other members of the faculty to conduct prospective cohort studies of critically ill patients with severe sepsis and acute trauma. Currently, his research focuses on understanding a novel association between the ABO blood group and risk of organ dysfunction (i.e. ARDS and acute kidney injury) in the setting of trauma and severe sepsis. His ultimate goal is to provide mechanistic insights into critical illness that can be translated to improved care for patients suffering from sepsis and ARDS.
