Research Description

We study mechanisms of adaptation to natural and anthropogenic stressors in marine mammals and pre-clinical models of disease at the molecular, cellular and organismal level. Our goal is to understand the role of oxidative stress and redox signaling in physiological adaptation and human disease. Current projects include 1) cellular and physiological consequences of chronic stress in marine mammals, 2) cellular mechanisms underlying the diving response and 3) role of peroxiredoxin 6 in acute and chronic inflammation.
