Profile/About Me

Our lab studies the diversity and evolution of animal function. We are interested in questions about:

• How animals (and their parts) work

• How the ways that animals work affect their ability to survive

• How animal function varies to meet the demands of different environments

• How animal function has diversified and changed through evolution

To answer these questions, most of our research examines vertebrate muscle and bone function during locomotion, with a major focus on reptiles (especially turtles and alligators), amphibians, and fishes. Other work includes studies of fish feeding, vertebrate paleontology, and the mechanics and evolution of deer antler.

We use a wide range of techniques in these studies, drawing on experimental biomechanics (high-speed video, strain, EMG, force platforms, mechanical property testing), morphometrics (allometry, mechanical models of recent and fossil specimens), phylogenetic comparative methods, and field sampling.

Our lab participates in several professional societies, and is especially active in the Society for Integrative and Comparative Biology (SICB), the Society for Vertebrate Paleontology (SVP), and the International Society of Vertebrate Morphologists (ISVM). I currently serve as Chair of the Division of Vertebrate Morphology for SICB. I am also on the Editorial Boards of the journals Proceedings of the Royal Society B, Integrative Organismal Biology and the Journal of Morphology, serve on the Board for Clemson's Bob Campbell Geology Museum, and facilitate activities for Clemson's Bob and Betsy Campbell Museum of Natural History.
