Research I am interested in the recovery of unconventional hydrocarbon resources and mitigating carbon emissions from fossil fuels via geological sequestration of greenhouse gases. My research group and I examine the physics of flow through porous media at length scales that vary from the pore to the laboratory to the reservoir. The organizing themes are flow imaging to delineate the mechanisms of multiphase flow (oil, water, and gas) in porous media and the synthesis of models from experimental, theoretical, and field data. In all of our work, physical observations, obtained mainly from laboratory and field measurements, are interwoven with theory.
Teaching My teaching interests center broadly around education of students to meet the energy challenges that we will face this century. I teach undergraduate courses that examine the interplay of energy use and environmental issues including renewable energy resources and sustainability. At the graduate level, I offer classes on enhanced oil recovery and the thermodynamics of hydrocarbon mixtures.
