My lab is fundamentally interested in the evolution of marine invertebrates with an emphasis on decapod crustaceans. We use morphological and molecular techniques to address questions related to their relationships, origins, biogeography, biodiversity, ecology, taxonomy, and conservation. My main research objectives include 1) decapod phylogenetics and genomics, 2) the evolution of systems and structures (ex. bioluminescence, vision, color), and 3) the identification of key morphological traits that promote diversification and speciation within this group.
