Research and Teaching

I will convert to a part-time position beginning in Fall, 2020, with all my teaching to be in the spring and at the undergraduate level.  Thus I am no longer taking on new graduate students. 

Sedimentary Petrology & Diagenesis

My research interests relate to the deposition and diagenesis of carbonate rocks, and the application of carbonate geology to the understanding of petroleum reservoirs. Principles of carbonate diagenesis, and porosity and permeability evolution, are common themes. Past studies focused on the processes of diagenesis as determined from the petrography and geochemistry of the diagenetic products, and when possible, the actual diagenetic fluids. Over my career I have analyzed early fresh-water diagenesis and mineralogical stabilization, burial diagenesis in the presence of seawater, mass transfer and cementation in regional fresh-water aquifers, the formation of microporosity in limestones, early compaction phenomena, the evolution of permeability with increased burial depth in Cenozoic limestones, origins of heterogeneity in the modern Floridan aquifer system, the origin of dolomite, and lateral variability in petrophysical properties of dolomites. I have a broad and continuing interest in evidence for self-organizing phenomenon in all aspects of sedimentary systems.

Geoscience Education

Over the last 10+ years, I have developed an interest in a variety of geoscience education areas as they relate to effective teaching and learning in collegiate settings. I have been involved in projects exploring what constitutes geoscience literacy, the role of the affective domain (motivation, self-efficacy, study habits) in student learning, the importance of active learning strategies and student-centered classrooms (including flipped classroom strategies).
