Research Interest

Why are there so many gobies? What traits have enabled goby lineages to diversify in almost every aquatic, marine, and occasionally terrestrial habitat on Earth? I use molecular and phylogenomic methods to infer phylogenetic trees of gobiiform fishes. I utilize my trees as data to test hypotheses about ecological traits that influence species and shape diversification. My preliminary results show that goby-invertebrate mutualisms are associated with rapid speciation of goby lineages, and freshwater invasions are related to increased rates of body size evolution.
