Current Research Interests

I am a paleontologist and a stratigrapher, and I’m interested in the long-term response of marine invertebrate communities and sedimentary environments to sea-level change and climate change. I use a combination of field work and computer simulation in my research. In my field work, I've used extraordinarily fossiliferous deposits to test a wide range of hypotheses about the controls on the diversity and structure of marine communities. My graduate students study the paleoecology of marine invertebrate communities of a variety of ages, as well as the stratigraphy and sedimentology of the rocks in which they are found. Currently, my students and I are studying the ecological assembly and history of the Jurassic epicontinental seaway in western North America.

Research Interests:

Currently, I am concentrating on an NSF-funded project on the common-cause problem, that both biodiversity and the completeness of the stratigraphic record are controlled by the same factors, such as eustatic sea-level change. The project includes computer simulation to make predictions about how sea-level change would affect the diversity of marine invertebrate communities, the structure of the stratigraphic record, and our perceptions of the fossil record. The project also includes a field study and a database study to test the predictions of these models.

I am also working on the ecological structuring of newly formed inland seaways, specifically focusing on the Jurassic Sundance Seaway of the western United States. My students and I are developing a regional sequence stratigraphic framework for the basin, investigating the biogeographic sources of the marine organisms that populated this seaway, and identifying the main factors that controlled the development and evolution of marine communities.
