I am Matt Joeckel and I have a 30% appointment in the Department of Geosciences, the remainder of my appointment being in the School of Natural Resources (SNR). In SNR, I work within the Conservation and Survey Division (CSD), Nebraska's state geological survey.

My research has focused on soils, paleosols, and weathering (especially in the contexts of climate and long-term change); stratigraphy and sedimentology, particularly with respect to regional Paleozoic and Mesozoic strata; environmental geology, and vertebrate paleontology. In recent years, I have engaged in considerable research on acid-rock weathering and mineral paragenesis in Nebraska and adjacent areas. I am also continuing research on sub-Pennsylvanian-cyclothem weathering profiles atop igneous rocks on the Nemaha Uplift in southeastern Nebraska and eastern Kansas. Together with colleagues from the University of Iowa and Iowa Geological Survey Bureau, the Kansas Geological Survey, and other institutions, I have been examining the regional sequence stratigraphy, palynostratigraphy, clay mineralogy, and stable-isotope chemostratigraphy of of the mid-Cretaceous Dakota Formation and associated strata in Nebraska, Kansas, and Iowa. Other ongoing research projects include stratigraphic, chemostratigraphic, and paleopedological studies of the Cretaceous Cedar Mountain Formation in Utah and the fluvial architecture of the Miocene Ogallala Group in Nebraska.

My duties in SNR/CSD include regional stratigraphic studies, mineral resources assessment and reporting, geologic mapping, surficial and environmental geology, and water supply. Currently, I serve as Outreach Coordinator for SNR.

I received my Ph.D. from the University of Iowa in 1993. A native Nebraskan, I returned to UNL in August of 2000, after having been an NSF postdoctoral fellow at the University of Tennessee in 1994-1996 and after having directed the Geology-Geography program at Bellevue University from 1996 to 2000.

I currently teach GEOL 100 Introduction to Geology, but in the fall semester of 2008, I will be teaching GEOL 110 Geology of Natural Hazards and GEOL 450/850 Surficial Processes, a survey course in geomorphology. In the School of Natural Resources, I have previously taught NRES 477/877 Great Plains Field Pedology.
