Population ecology of coral reef organisms

Research Interests

I am interested in the ecology of coral reef organisms particularly the population ecology of octocorals (soft corals and gorgonians). I and my students have conducted studies ranging from the feeding ecology of butterfly fish to the evolution and systematics of corals, and we use techniques that range from scuba based observations to DNA sequencing. Much of my current reseach employs a combination of field experiments and molecular studies to examine the reproduction and recruitment of octocorals on Caribbean reefs.
