Professor Sposito has been elected a Fellow of six international scientific societies and in 2008 was designated a “Legend in Environmental Chemistry” by the American Chemical Society, the world’s largest scientific organization. He has served as an Associate Editor for Reviews in Geophysics, Advances in Water Resources, Sciences Géologiques, Geochimica et Cosmochimica Acta, and Geoderma.
Professor Sposito teaches courses on soils and the water cycle as related to the food system. He also teaches an undergraduate course on environmental studies with Professor Robert Hass. His research interests include environmental geochemistry, especially surface chemistry and colloidal behavior; mathematical models of transport in porous media; and molecular simulations of the structure and reactivity of layer type minerals.
