I am a whole organism biologist with a particular interest in copepod crustaceans. Copepods are ubiquitous in aquatic systems but all radiated from a hyperbenthic origin in shallow marine waters. Multiple lineages of copepods colonized the open pelagic, colonized fresh and subterranean waters, and colonized almost all other metazoan phyla as hosts as they adopted parasitism as a mode of life. The overarching aim of my research is to identify and understand the drivers generating the patterns of copepod biodiversity on the largest scales. My current focus is primarily on parasites: the repeated evolution of parasitism in copepods provides opportunities to examine the usage of different host taxa and to explore speciation patterns around major host colonization or host switching events.
