HighlightsHannan currently teaches classes in geology, biology, statistics, and research methods for the SEM, Natural Resources, Environmental Science, and Nursing (RN) degree programs. Specifically, Hannan is interested in Cenozoic stratigraphy, vertebrate paleontology, and predator-prey relationships in northern Great Plains mammals. Hannan is also interested in the ecological, human, and social impact of declining water supplies, water contamination, and prolonged drought in the northern Great Plains region.
Geological mapping and lithostratigraphic revision, redefinition, and redescription of the White River, Arikaree, and Ogallala groups in northwestern Nebrska, southwestern South Dakota, and northeastern Wyoming.
Systematics, evolution, paleoecology, and taphonomy of Cenozoic (particularly Oligocene) mammals and the management of vertebrate fossil resources on Tribal and Federal lands in the northern Great Plains region.
The evolution of prey body-size selection, diet, and taphonomic modification of prey skeletons by Great Plains carnivores, including mountain lions, coyotes, and swift foxes (with Alessandra Higa).
