Get To Know Lene H. Petersen

What in your life drew you to your current field of study?

As I grew up near the North Sea (Denmark), I have always been fascinated by the ocean and the creatures living in or near it. However, even though the animals themselves were captivating, I have always wanted to learn more about the underlying (physiological, biochemical, genetic) mechanisms that enable animals to live in diverse habitats and cope with changes in their environment.

The main research focus of my lab is to understand how environmental (temperature, hypoxia, salinity) and anthropogenic (pharmaceuticals, contaminants) stressors affect animal physiology.  In particular, we are interested in understanding cardiovascular, respiratory, reproductive and metabolic responses to stressors.  We study effects of short (few hours/days) and long-term (weeks) stressors (individual or multiple) at all levels of biological organization (molecular, cellular, organ and whole-organism), and developmental stages (early life stage to adult).  Understanding how perturbations in the animal’s environment mechanistically affect survival is important in assisting conservation efforts.  We are currently studying physiological responses in American alligators and local Gulf of Mexico fish species.

What do you hope your students gain from studying or working with you?

My hope is to create excitement and curiosity about how animals mechanistically solve challenges such as changing oxygen levels, salinity, temperature or pollutants. I always try to encourage critical and independent thinking and innovative ways of studying animal physiology.

What are you passionate about in your personal life?

I enjoy spending time with my husband and our standard poodles, Ernie and Beau! We love taking the dogs to the beach and teaching them tricks at home.
