Research and Academic Interests:

My research focuses on a stratigraphic approach to groundwater flow and contaminant transport modeling. My students and I work to construct detailed characterizations of fluvial aquifers using basin analysis tools (a sequence stratigraphic approach). Currently, we apply indicator geostatistics within the stratigraphic framework, but we’re always looking for something better!

My teaching focuses on student participation in their learning, and my classrooms tend to be active. Classes include hydrogeology, aquifer and petroleum reservoir characterization, groundwater modeling, environmental systems, and (one of my favorites) the Blue Planet (a general course on environmental earth science)!
