Positions

Overview

  • I was trained as an invertebrate zoologist with strong interests in life histories, behavior, and defensive strategies utilized between members of predator-prey associations. My teaching and research focus primarily on marine species and communities and while most of my studies are done in the Gulf of Maine, I have experience in a wide diversity of habitats (Panama, Chile and Indonesia in 2005). My research is most accurately described as quantitative and manipulative natural history. The focus is on organisms and how they are adapted to their environments. This would be in contrast to a more theoretical approach that places primary emphasis on testing general models. Both are important - I just happen to like living organisms first.
