Profile: Ashaki Rouff

Associate Professor

Department of Earth & Environmental Sciences

My research explores the behavior of inorganic and organic contaminants in aqueous geochemical (soil, sediment) and engineered (wastewaters) settings. The mechanisms and kinetics of contaminant interactions with mineral phases determine the mobility and bioaccessibility of these species in affected systems. Understanding these processes has important implications for predicting the fate of contaminant species in the environment.

We use laboratory-based model systems, field work, and advanced molecular-scale techniques; as applied to the areas of contaminant geochemistry, urban geochemistry, and sustainable geochemistry. Current research topics include the assessment of heavy metal contamination of human-impacted soils, and the evaluation of alternative mineral fertilizers as related to the sustainable use of natural resources.
