Research Interests

Impact of major trauma on organ injury

Research Activities

Trauma victims are at increased risk of developing organ injury in the early post-trauma period. Our research group studies the cellular and molecular mechanisms whereby resuscitated hemorrhagic shock is able to predispose trauma victims to the development of organ dysfunction. We utilize multiple experimental approaches including in vitro systems to study cellular mechanism as well as in vivo models to test relevance at the organ and whole body level.
