Research Interests
My work centers on description of the insect fauna of the Coal Creek Member of the Middle Eocene Kishenehn Formation in northwestern Montana. I am also interested in defining the biological and geological processes that resulted in the preservation of these insects and the original biomolecular components that are found in the fossils of the Kishenehn Formation.
