"Environmental engineers are the environmental gatekeepers. We manage the interface between the industrial and natural worlds to ensure quality of life for all, today and in the future.
Craig H. Benson, Dean, School of Engineering
My expertise falls in the discipline referred to as geoenvironmental engineering. This discipline is at the interface of the built and natural environments, and deals with issues in the subsurface or interactions between conditions at the earth’s surface and the subsurface. In most cases, the important objective is to protect soil and ground water or to engineer systems that reduce emissions or save energy. Achieving these objectives requires knowledge of the mechanisms controlling energy and mass transfer in the subsurface and development of creative approaches to control the rate at which energy and/or mass is transferred. These principles are applied to controlling contaminant migration in the unsaturated zone and ground water, managing the movement of heat and water in near-surface soils, and assessing energy usage and emissions associated with geological engineering structures at the interface of the earth’s surface.
My research in geoenvironmental engineering fits in three broad classes: design and assessment of environmental containment systems for municipal, hazardous, and radioactive wastes; reuse and recycling of industrial byproducts for sustainable construction applications; and sustainability assessment of geological and civil engineering systems. In each of these areas, we emphasize a full range of study from basic theory to practice and address energy and mass transfer issues. Our research includes fundamental laboratory studies, development of computer models, and practical field demonstration of new technologies. In many cases, our research findings are validated at full-scale in operating facilities or infrastructure in collaboration with industry and/or government agencies.
