Research Overview
My research is mainly centered around trophic interactions between organisms. This involves dietary composition, feeding habits and consumption rates of invertebrates, macroalgal-herbivore interactions, stable isotope analysis of food web structures, etc. It also involves chemical defenses of macroalgae and invertebrates against grazers and predators. I am generally interested in shallow water community diversity, dynamics and ecology, especially in both polar regions, and in deep-sea communities. Most of my shallow water work uses scientific diving as a research tool.
