My research primarily focuses on three areas – (1) fluvial sedimentology and stratigraphy in a sedimentary basin context, (2) the influence of aquifer heterogeneity on groundwater flow and contaminant transport, and (3) diversity in the geosciences. In fluvial sedimentology, my students and I, along with colleagues at the University of Aberdeen, University of Glasgow, and UNM, have identified over 700 continental sedimentary basins around the world. From satellite imagery and ground truth characterization, we are evaluating facies distributions from fluvial deposition in these basins. Most of this deposition is occurring on distributive fluvial systems (DFS), so facies models as we know them must be revised to understand the variability recognized on the DFSs. Our manuscripts in Geology (2010), Journal of Sedimentary Research (2010), SEPM Special Publications 97 (2011) and 104 (2013), and Geomorphology (2015) explain the fundamentals of these concepts.
