Research Interests
- My recent research falls into one of two broadly defined
disciplines: Sedimentology and hydrogeology. I have a long-standing
interest in the stratigraphic and sedimentologic attributes
of Paleozoic strata in the central midcontinent of North America.
The depositional origin of enigmatic, Lower Paleozoic sheet
sandstones, and Cambrian mass extinction events, have been
topics of particular interest. Over the past few years I have
also been increasingly involved in groundwater research. Most
of this latter work involves hydrogeologic characterization
of the Paleozoic aquifer system of southeastern Minnesota
through the integration of outcrop, core, and borehole geophysical
data.
