My research interests focus on the interactions among coral reef organisms and the shifting baselines of coral reef ecosystems. Most of my time is spent researching the ecology and biodiversity of marine amphipod crustaceans inhabiting coral reefs worldwide. My specialty is in a potentially eusocial and/or harem-based amphipod family that is endo-commensal with sessile marine invertebrates, focusing on taxonomic, systematic, ecological, and phylogenetic studies of this deep lineage based family in tropical ecosystems. More recently, I have been involved in investigating the effects of invasive invertebrates on coral reef ecosystems.
