Associate Professor

Teaching Interests

My main teaching interests are in ecology and conservation, behavioral ecology, marine biology, and invertebrate zoology. I also enjoy teaching courses in computer simulation modeling and ecological statistics.

Research Interests

My training and interests are in marine biology and ecology. My research explores two broad areas. First, I study the responses of animals to environmental changes caused by humans (climate change, habitat destruction, invasive species, pollution, etc.). This includes behavioral and physiological responses of individual animals, as well as extinction of populations. Second, I study the role of individual variation within populations, such as differences in animal personality and differences in energetics, and how this individual variation influences population and community interactions. My research uses a wide range of animals in freshwater and marine habitats, including zooplankton, crabs, shrimp, and polar bears. My work also includes a wide range of approaches, from field and laboratory experiments, to physiological analyses, to computer simulation and mathematical modeling.
