Our lab is primarily interested in understanding how organisms adapt to environmental change and documenting the factors that facilitate and constrain evolutionary diversification. We do not restrict the meaning of diversification to an increase in the number of species, consequently we spend a good deal of time trying to understand the processes that lead to patterns of morphological and genetic diversity within species. Our lab use many different tools to tease apart the complexity of biological systems, including traditional and geometric morphometrics to study morphological variation, and genetic markers such as microsatellites or mitochondrial DNA sequences to study molecular variation. Members of our lab work mostly with fishes and conduct research in temperate and tropical systems from Alaska to Ecuador.
