Craig H. Benson, Ph.D., P.E., NAE, University of Virginia School of Engineering and Applied Science

Dr. Benson’s expertise falls broadly 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 objectives are protecting soil and ground water or engineering 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.

His research in geoenvironmental engineering fits in three broad classes: sustainability assessment of geological and civil engineering systems, reuse and recycling of industrial byproducts for sustainable construction applications, and design and assessment of environmental containment systems for municipal, hazardous, and radioactive wastes. 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.

Sybil Sharvelle, Ph.D., Colorado State University

Sybil Sharvelle, Ph.D. has served as a faculty member at Colorado State University (CSU) since 2007 with research on anaerobic digestion for methane capture and use. Her expertise is in the area of biological process engineering. While pursuing a M.S. degree at the University of Colorado Boulder, she worked on a project funded by NASA to develop a biological processor for treatment of urine-soap wastewater expected to be generated at the International Space Station. This research led Dr. Sharvelle to the Ph.D. program at Purdue University where she was part of the NASA Specialized Center for Research and Training (NSCORT) focused on advanced life support (ALS) research. The goal of center was to recycle valuable resources such as water and air, while recovering important nutrients. Her specific project was a biological processing unit for simultaneous treatment of graywater (laundry and hygiene wastewater) and waste gas contaminated with high levels of ammonia and hydrogen sulfide. Dr. Sharvelle’s previous research experience in closed loop life support led her to research in the area of sustainable water and waste management. Dr. Sharvelle was hired by CSU to provide expertise and serve as an extension specialist in the area of livestock waste management. She has developed an online decision tool for feasibility of on-farm anaerobic digestion. She is also developing a new technology for anaerobic digestion of dry waste, including municipal and agricultural wastes, which would improve the feasibility of waste conversion to methane biogas. Dr. Sybil Sharvelle has nine years of experience working on graywater projects. Her graduate studies were funded by NASA to optimize biological waste processing systems that would treat graywater with the end goal of potable reuse. The waste treatment concept employed entailed separate source collection and treatment of graywater, urine, and fecal material. Dr. Sharvelle’s experience in closed loop recycling of resources is very valuable for implementation of sustainable development concepts for urban water management. Dr. Sharvelle is currently working on sustainable urban water management including graywater reuse, reclaimed water reuse, development of models to estimate water savings associated with urban water conservation practices. Dr. Sharvelle also has several years of experience working on waste conversion to methane through anaerobic digestion.
