Evolution of marine invertebrate life histories, larval ecology, phylogeography, morphological integration through metamorphosis, invertebrate systematics.
My current research focuses on the evolutionary causes and consequences of mode of development in marine gastropods. Mode of development (planktonic vs. benthic, feeding vs. non-feeding, encapsulated vs. free-living) has important consequences for dispersal, gene flow, speciation rates and extinction rates. However it is unclear what factors maintain the stunning diversity in mode of development that we observed in many groups of marine invertebrates. My research focuses on documenting the geographic and phylogenetic patterns in mode of development and combining these patterns with the results of laboratory experiments to test hypotheses about the factors driving its evolution.
Director, Bocas del Toro Research Station (BRS)
I have been the director of the BRS since 2002, during which time the station has grown from a small field site with limited facilities to the world-class tropical research station that it is today. The station receives over 300 scientific visitors from 20-25 countries each year and we offer support to marine, terrestrial, geological and anthropological research. My pet project at the station, the Training in Tropical Taxonomy program, is helping to train a new generation of taxonomists working on tropical marine organisms. The Bocas del Toro Biovidersity Database lists over 6000 species from the province and provides information, photos and locality information for most of those species. Current development of the outreach program, including web-resources for teachers and a self-guided nature walk will keep me busy in the near future.
