Acute renal failure is a frequent and serious complication of septic shock in humans. My research is focused on the study of animal models of renal injury associated with sepsis. Studies are directed toward understanding the biochemical and physiological mechanisms triggered by sepsis that lead to cellular injury and organ failure. Our primary interests are in understanding the development of oxidant stress caused by reactive oxygen and nitrogen species as mediators of renal injury and evaluating new therapeutic approaches to prevent renal injury or accelerate recovery.
