Current Research Interests
1. Allocyclic controls and architecture of modern and ancient alluvial valleys and fluvial systems with special reference to the modern, sandy, braided Niobrara River, Nebraska and the Cretaceous of the Rocky Mountain Region.
2. Testing concepts of sequence stratigraphy using outcrop, subsurface and flume (analog) experiments.
3. Developing predictive analog models for estimating reservoir shale and mudrock seal capacity and seal/flow barrier distribution for use in oil and gas exploration and risk analysis/mitigation.
4. Depositional environments, stratigraphy and diagenesis of siliciclastic rock sequences as applied to exploration for petroleum, coal, uranium and groundwater.
5. 3D seismic geomorphology.
