Brief Biography

Professor Garrabrants holds a doctoral degree in chemical and biochemical engineering and is currently an Associate Research Professor of Civil and Environmental Engineering at Vanderbilt University in Nashville, TN.

His research focuses on development of leaching tests and assessment approaches for estimating the fate and transport of constituents from soils, sediments and wastes. He continues work to improve understanding and achieve acceptance of standardized approaches for environmental impact assessment of solid wastes, construction materials, soils, and sediments. He is a technical lead for the United States Environmental Protection Agency research to adapt the approach of the Leaching Environmental Assessment Framework (LEAF) toward organic contaminants in solid wastes.

Other research interests include (i) beneficial reuse of waste materials in construction, (ii) release assessment approaches for semi-volatile organics in soil/cement mixtures (e.g., in-situ stabilized soils), (iii), physiochemical models for estimating source terms for risk assessment and risk evaluation, and (iv) leaching chemistry and long-term durability of cement-based solidification/stabilization (S/S) waste treatment and cementitious engineered barriers for nuclear waste disposition.

Professor Garrabrants actively participates in the activities of ASTM International D-34 Committee on Waste Management serving as the Committee Chair, Vice Chair and, currently, Secretary. He has served on Expert Technical Review panels to draft regulatory guidance for solidification/stabilization of contaminated soils for the Interstate Technology and Regulatory Council (ITRC) and to review Department of Energy approaches for demolishing and disposition of the Y-12 plant buildings at Oak Ridge. He holds memberships in several professional societies including the American Institute of Chemical Engineers, American Society of Civil Engineers, and the American Chemical Society
