I am an ichthyologist by training, and I further specialized in understanding macroevolutionary dynamics using a combination of applied methods in comparative genomics. Research in our lab is broadly concerned with the evolutionary biology of fishes and is oriented around understanding the genetic basis of adaptive traits, testing evolutionary hypotheses, uncovering drivers of morphological and lineage diversification, and documenting the diversity of fish faunas. Our research approach is currently intensifying the implementation of genome-scale approaches for robust inferences of phylogeny and phylogeography. We also use phylogenetic comparative methods and comparative genomics in combination with unified approaches that integrate neontological and paleontological evidence to address a broad array of questions in macroevolutionary research.
