Fossil Specialty (if any)
Ordovician brachiopods and their friends, Conchostracans
Favorite Collecting Site(s) or Region(s)
The Ordovician of the world! But especially the Cincinnati region. I grew up in Cincinnati, and no other fossils have ever been able to be usurp their central position in my heart. I have collected specimens on all seven continents for projects spanning marine paleobiology of invertebrates (mostly brachiopods) through lacustrine crustaceans of the Mesozoic through Cenozoic deposits.
I am a faculty member in the Geological Sciences department at Ohio University in Athens, Ohio. My research employs paleogeographic, paleoecology, and phylogenetic methods to examine the response of species to environmental change. I am particularly interested in how species alter their ecological niches and geographic ranges and well as better understanding the process of speciation. I teach courses on Earth History, Paleontology, Paleoecology, Paleobiogeography, and Carbonate Depositional Systems.
