Welcome to the Johnston Research group!

Research interests in the Johnston Group are focused on understanding the surface chemistry of soil and environmental particles in the broader context of biosphere science. Using optical, laser-based, and structural methods we study soil and environmental particles and the interaction of both natural and anthropogenic compounds with soil and environmental particles.  Current research projects range from fundamental studies of clay minerals and hydrous oxides to earthworms, carbon sequestration and emission, environmental fate and transport of antibiotics, aryl hydrocarbon receptor ligands (e.g, dioxins) and pesticides in soil.
