My research focuses on taxonomy, paleoecology, stratigraphy, sedimentology, taphonomy, and geochemistry of Paleozoic shales and carbonates. Past research concentrated on the stratigraphic context, preservation and taxonomy of a new Burgess Shale-type deposit from the Mackenzie Mountains, northwestern Canada, as well as geochemical anomalies of the exceptionally preserved interval. More recently, my research concentrated on the taxonomy, stratigraphy and paleoecology of the Cambrian Spence Shale in Utah and Idaho, and the Mississippian Lodgepole Formation of Montana.

I am the Collections Manager at the Earth and Mineral Sciences Museum & Art Gallery at Penn State University and a research affiliate with the Division of Invertebrate Paleontology at KU. My main interests are Paleozoic Lagerstätte-type deposits, Museum Collections, Problematic Cambrian Soft-bodied Taxa, Trace Fossils and Phytosaurs.
