Research Interests

For all the talk about coral reefs being “rainforests of the sea”, remarkably little is known about exactly how many species live on reefs, or why reefs are so diverse, or why some areas harbor more diversity than others. My interests lie in figuring out what lives on reefs, and the engines of diversification that drive the evolution of reef-associated organisms. Small Pacific islands and the Coral Triangle biodiversity hotspot are enduring interests of mine – why are they so diverse, where do the biogeographic boundaries lie, what special ecological traits promote rapid speciation, and what new species remain to be discovered? I am also interested in connections between biodiversity, ethnobiology, and resource management and conservation, because biodiversity hotspots also tend to be areas with high cultural diversity and are also the most threatened by human encroachments.

In my research, I link modern molecular genetic tools with classical taxonomy. I’m also a strong believer in spending as much time in the field as one possibly can, as this is the best way to really get to know a group and an ecosystem. Taxonomically speaking, I’ve a special place in my heart for crustaceans – I’ve worked extensively on hermit crabs and coral-dwelling barnacles. But I’m interested in the evolution and natural history of any and all tropical marine invertebrates. They are all cool and fascinating to me.
