My research involves the diversification and biodiversity of life forms during the geologic past, especially the Paleozoic and Quaternary; biomineralization in early animals; fossilization processes and exceptional fossil preservation; the relationship between geologic and biotic changes during critical intervals of geologic history; and methods of global stratigraphic correlation. Many of the articles shown here are available online, but pdf copies can be provided upon request.
