At UT, I teach introductory geoscience courses and coordinate teaching labs and our graduate teaching assistants. I am the point of contact for our GTAs in their everyday work, and provide them with professional development opportunities in their teaching role. My primary interests within the geosciences are paleontology and sedimentology. My research has focused on the intersection between the two--a field known as ichnology that deals with the tracks, trails and burrows ancient organisms made (trace fossils) as they interacted with the substrate. I enjoy most the analysis of discrete trace fossils and past work has included interpretation of some of the earliest marine macroboring behavior, fish and arthropod interactions in Pleistocene glacial lakes, and reconstruction of terrestrial communities of the Late Paleozoic that are represented solely by their trace fossils.
