Our research focuses on the evolution of the multivariate phenotype. We are interested in understanding micro- and macroevolutionary patterns of phenotypic diversification, and the historical and ecological processes that are responsible for them. We use a comparative evolutionary framework to attain these goals, directing our empirical work towards vertebrates, with an emphasis on plethodontid salamanders. We also develop new theoretical and analytical approaches for quantifying the multivariate phenotype, and for elucidating patterns of phenotypic evolution and change.
