I am a vertebrate paleontologist most interested in the evolutionary history and paleobiology of dinosaurs. I am most deeply invested in understanding the long-necked, herbivorous dinosaurs known as sauropods. This group existed for more than 160 million years, was globally distributed, and included the largest terrestrial vertebrates of all time. As such they are perfect fodder for my interest in dinosaur evolution and offer a wealth of data on the biological consequences of living life at large size. In terms of broader paleobiological questions, I use bone histology to explore and reconstruct patterns of the evolution of body size, growth rates, and life history strategies among dinosaurs, their living relatives, and their modern analogues. My research on dinosaurs takes me around the world, both to museums and in the field, from the Triassic-Jurassic of Zimbabwe, to the Jurassic of Montana, to the Cretaceous of Argentina and Madagascar. I really enjoy working with students, and have undergraduate collaborators on many of my research projects. I am jointly appointed in the Biology Department at Macalester College, and teach a selection of courses that relate to my academic interests: (1) Dinosaurs (GEOL 101); (2) Vertebrate Paleobiology and Evolution; (3) Biodiversity and Evolution (BIOL 270), and (4) Comparative Vertebrate Anatomy (BIOL 394).
