Research Interests

My lab is currently pursuing three projects:

Paleoecology of North American elephant relatives (mastodons, gomphotheres) that once inhabited the Florida peninsula.  Dental deposits are removed from the molars of these fossils and processed for plant remains and other indicators of feeding habit.  Ultimately, every small piece we can put together of this puzzle will help us understand why ancient and modern megafauna become extinct.

Burrowing behavior in generalist rodents, especially juveniles.  Pups are very active, possibly instinctive burrowers and natal burrowing may be a significant contributor to parental and colonial tunnel systems.  Current study subjects are Sprague-Dawley rats and eastern chipmunks.

In addition to the above research, my lab is conducting a long term survey of small mammals at a meadow restoration site.  Mammals are live-trapped for data on species diversity and population dynamics.  As the meadow develops, we expect to see changes in these parameters that may be compared with similar restoration efforts.
