Areas of Interest

Invertebrate Paleontology

Research

My research interests lie at the intersection of paleontology, ecology and evolutionary biology. Patterns and processes of mass extinction, with special reference to Lower Paleozoic trilobite faunas of North America, are a primary focus. Other research deals with evolutionary radiations following mass extinctions and with the changing role of trilobites in Paleozoic marine communities. I have also published extensively on trilobite systematics and biostratigraphy. I have additional interests in the taphonomy of marine depositional systems, as well as in stratigraphy and sedimentary facies analysis.  All of my research is strongly field-based, and my students and I work on Cambrian and Ordovician successions throughout North America.  Funding is primarily from the National Science Foundation.
