Current research includes study and modeling of architecture of reefs, basin analysis, global supply and demand of petroleum, classification and anisotropy of reservoirs, and processes in the formation of carbonate rocks and evaporites. Carbonate sedimentology and diagenesis. Geomorphology, Pleistocene geology, geochronology. Current research includes beryllium-10 dating of glacial erratics and erosion surfaces. Physical geography, soils geomorphology, Quaternary studies, field methods.
Current research includes paleosols as paleoclimatic and paleoenvironmental indicators.
Sedimentology with emphasis on terrigenous clastic and volcaniclastic rocks Current research includes the effects of facies and diagenesis on oil production from sandstone reservoirs and the deposition and diagenesis of sediments in volcanic terranes. Ph.D., University of Kansas, 1985. Stratigraphy and sedimentology. Current research includes sequence stratigraphy and modeling late Paleozoic cyclothems of the Midcontinent. The five academic departments, the Natural History Museum, and the Kansas Geological Survey offer a number of teaching, curatorial, and research assistantships to students, and the Department of Geology annually offers at least one research fellowship that is funded by the petroleum industry.
