My research interests are in the area of environmental physiology and biochemistry, in particular the responses of aquatic organisms to low oxygen (hypoxia). My students and I have used an integrative approach, combining physiological ecology, metabolic biochemistry and molecular biology, to order to better understand the responses of estuarine and freshwater fishes to hypoxia.

Currently, I am very interested in oxygen-regulated gene expression and I am developing approaches to study this process a couple of “model” groups, killifish (Fundulus spp.) and zebrafish (Danio rerio). A related area of interest is mechanisms of metabolic regulation in animals during changing, or stressful, environmental conditions.
