My research spans phylogenetics, phylogeography, and population genetics of North American amphibians to better understand the processes underlying diversification.
Few observations in biology arouse as much curiosity as those on the shape, function, and mechanics of morphological structures. Evolutionary morphology embraces the “how” of morphology, such as the mechanics of how an animal can bite into a hard object with extraordinary force without knocking out its own teeth or shattering them. It also embraces the “why” of morphology, retracing the patterns of evolution in features to understand how a few basic morphological patterns gave rise to the stunning diversity we see in groups from molluscs to mammals to plants. The “how” and the “why” combine to reveal the ways in which organismal evolution has transformed structures and promoted novel functions as well as patterns of association between morphological features and either geographic area or habitat.

My primary area of interest is evolutionary morphology, with the major focus on the form, function, development, and evolution of the vertebrate musculo-skeletal system.

My research program involves topics within the broadly defined area of biodiversity study. I am particularly interested in (1) the interplay of ecology and evolution that determines the form and function of plant life on Earth and (2) the use of biodiversity research specimens and digital information about them to bring that interplay into sharper focus.

I seek to understand the origin of biological diversity. We study the evolution of morphological traits, whether for reconstructing phylogenies, biomechanical studies, quantifying the patterns of morphological diversity (disparity) over time in as clades evolve, or the underlying patterns of correlations among traits.
I study all aspects of morphometric research, including theoretical morphometrics, the development of morphometric software, and the application of morphometric analysis to a number of problems.
