Research Interests
As a vertebrate paleobiologist, my focus is the evolution of form, function and ecology in organisms, both living and extinct. I study living species as a key to understanding extinct species and am drawn to the fossil record because of its unique attributes. First, it provides the only record of long-term evolutionary change in form, matched perhaps in magnitude only by the history of genetic change preserved in the genome. Second, it provides a window into life and ecosystems prior to the alterations and biases engendered by anthropogenic forces and recent Pleistocene extinctions. Third, it presents us with species and morphologies that are no longer present, such as dinosaurs and sabertooth cats, and thereby expands our understanding of life?s potentials beyond what we can observe today.
Much of my research has focused on large predatory mammals. Large predators on land and sea are receiving much attention among ecologists because they act as major drivers within their ecosystems and many are threatened with extinction. As top-down regulators, they are pivotal players in trophic cascades that affect both plant and animal distributions and abundance. Modern species evolved within much more diverse and complex guilds of large predators that included species such as short-faced bears, sabertooth cats, and dire wolves. To better understand both the dynamics of extant predator communities and the adaptations of individual species, I have explored the fossil record of carnivores from both ecological and evolutionary perspectives, sometimes focusing on guilds of species in distinct time horizons, and other times focusing on the evolutionary trajectories of species over millions of years. Below I list four recent areas of research that exemplify the work in my lab.
1. Macroevolutionary dynamics of large carnivores
2. Evolution of mammalian feeding adaptations
3. Function and evolution of mammalian nasal turbinate bones
4. Molecular and morphological evolution within the Carnivora.
