Research in the Fish Evolution lab is broadly concerned with the evolutionary biology of fishes and is oriented around five major aims: (1) inferring relationships and testing evolutionary hypotheses in the context of such relationships, (2) uncovering drivers of morphological and lineage diversification, (3) elucidating patterns and processes in spatial and temporal distributions of species and populations within species, (4) understanding the genetic basis of adaptive traits, and (5) documenting the diversity of fish faunas. Our research approach currently implements high-throughput sequencing technologies for robust inferences of phylogeny and phylogeography, and integrative approaches that combine neontological and paleontological evidence to address macroevolutionary questions using phylogenetic comparative methods.

Previous and ongoing projects have focused on unraveling the pattern and tempo of fish evolution using molecular and fossil-based data, addressing the classification of "all fishes", uncovering the factors driving diversification and morphological evolution in relation to habitat transitions (e.g., marine and freshwaters), understanding the sources of phylogenetic conflict in genome-wide data, identifying barriers of marine fish connectivity in the Caribbean, testing hypotheses about the timing of divergence in transoceanic clades, assessing species boundaries, describing new species, among others.
