My work fits broadly into the fields of earth history and paleobiology. My interests span a relatively diverse group of topics, however most are united in that they are concerned with how ecosystems and their component taxa evolve and respond to changes in the physical environment. Research topics have spanned the fields of paleoecology, paleoclimate, evolutionary paleobiology, and stratigraphy. A specific area of interest is biotic and environmental change during the Paleogene (~65-24 million years ago), and field projects are ongoing in the US Gulf Coast, Seymour Island on the Antarctic Peninsula, and the Belgian Basin. I am also interested in the geochemistry of accretionary biogenic carbonates (e.g., mollusk shells), and what high-resolution microsampled records can tell us about the life histories of ancient organisms and the environments in which they lived. Other interests include the long-term dynamics of ecological assemblages and environmental change associated with intervals of faunal stability and turnover. I am a member of the Paleobiology Database (www.paleodb.org), and in that capacity am interested in how the architecture and composition of the sedimentary record influence Phanerozoic diversity.

Examples of accretionary biogenic carbonates that can be sampled at high resolution using the MicroMill: When cut and polished, these structures reveal growth banding much like that seen in tree rings. Detailed climate and life history information stored in these structures can be revealed through microsampling and stable isotopic analysis of the aragonite in individual layers. |

| Nope, the tide has not gone out and exposed these clams in their sandy home. These are 50 million year old Venericardia from the Hatchetigbee Formation in Alabama, beautifully preserved in life position and fortuitously exposed along the Tombigbee River banks. The Gulf Coast Paleogene is famous for its fossils. | |

The Paleoecology Lab at SU features a Merchantek MicroMill, a microsampling device that allows high-resolution sampling of accretionary biogenic materials for stable isotope analysis. A number of samples can be collected in sequence within a series of growth increments, e.g., in a mollusk shell or coral skeleton, that record intra-annual variation in composition and can allow for the reconstruction of seasonal temperature changes experienced throughout the life of the organism. All of the facilities needed for preparation of samples (sectioning, mounting, polishing) are available in the laboratory as well. In addition, the lab includes facilities for screen-washing bulk samples and cabinets for storage of paleontologic collections. |
