Research Program

 •3-D characterization and modeling of carbonate depositional systems through the integration of high-resolution outcrop and subsurface data combined with comparative sedimentology from modern environments.
•Interplay of diagenesis and petrophysical signatures of carbonates within a sequence stratigraphic framework.
•Integration of sedimentology, diagenesis, and high-resolution sequence stratigraphy to evaluate the effects of variable sea level change on the depositional record of carbonate and mixed carbonate/siliciclastic depositional systems.




My main interests revolve around the evaluation of carbonate depositional systems through an integrated sequence stratigraphic approach; by combining sedimentologic, diagenetic, and petrophysical analyses of modern and ancient depositional systems (outcrop and subsurface) to better constrain the 3-D evolution of these systems through time. While many of the questions being addressed are fundamental in nature, results may also be directly applicable to problems faced within the petroleum and groundwater industries: for example the lateral and vertical distribution of fluid-bearing strata and impermeable horizons. In addition, I continue to have interest in evaluating the sedimentologic and diagenetic responses of carbonate systems to varying frequencies of sea level change (i.e. icehouse vs. greenhouse periods of Earth's history). Current research locations include the MidContinent of the USA, the Bahamas, Paradox Basin of Utah, Wind River Basin of Wyoming, and the Michigan Basin.
