Director of the Bowdoin Scientific Station on Kent Island and Adjunct Assistant Professor of Biology
I am a marine vertebrate ecologist, with interests ranging from behavioral ecology to community ecology. I have studied foraging ecology, sound production, and habitat selection of fishes and marine mammals; food web dynamics; the application of passive acoustic techniques to fisheries science; and the ecological effects of toxic red tides on dolphins and fishes.
Since 2005, my research has focused mainly on the ecological effects of harmful algal blooms (HABs), often called red tides. This research interest developed out of necessity after an intense red tide caused massive fish kills on Florida’s Gulf Coast, halting several projects that I was conducting on the interactions between bottlenose dolphins and their prey.
As director of the Bowdoin Scientific Station, I hope to continue the station’s high level of productivity in avian and terrestrial ecology, and to expand its studies in marine ecology. In particular, I would like to develop active research programs in intertidal ecology, fish and marine mammal acoustics, and Alexandrium red tides (the type of HAB that is common in the Gulf of Maine and Bay of Fundy).
