Marine Geology/Paleontology

My research program is conducted in modern and ancient marine environments. Since 2003 I have worked with colleagues at the University of Western Australia (Perth) and the University of Queensland (Brisbane) to better understand the response of reef corals to present and future climate change. I have recently begun a project in Curaçao (Netherlands Antilles) examining reef coral succession in a region of low hurricane frequency. Finally, I have constructed a large literature-derived database on coral occurrences in fossil (Late Pleistocene, Holocene) and modern reefs in the Caribbean region. See initial analyses of reef crest and mid-slope environments.

I have also been involved in extensive reef survey work in modern environments. Much of this work is an outgrowth of my research involving the sedimentologic and biologic influences on the preservation potential (taphonomy) of marine invertebrates. I have applied the results of my research to currently salient issues including coral reef management and the response of coral communities to climate change, as well as more "traditional" paleontologic issues including paleoecologic reconstructions, evolutionary histories and patterns of diversity of echinoid echinoderms.
