Research Interests

Main research focus is to understand effects of environmental (temperature, hypoxia) and anthropogenic (pharmaceuticals, contaminants) stressors on fish cardiovascular, respiratory and reproductive physiology.  Effects of short and long-term stressors (individual or multiple) are studied at all levels of biological organization (molecular, cellular, organ and whole-organism), and developmental stages (early life stage to adult).

More recently, Dr. Petersen’s research interests have expanded to conservation physiology. Non-invasive endocrinology techniques (saliva, skin and claw clippings, feces/urine) are used to assess levels of glucocorticoid and reproductive hormones (e.g. corticosterone, testosterone) in wild and captive (zoos/aquaria) animals.  Current model organism is the American alligator.
