Biography
Robert Stallard has worked as a scientist in the National Research Program of Water Mission Area since 1987.He studies how land-cover and climate change affect water movement through soils, weathering, and erosion, and how these, in turn, affect the composition and dispersal of dissolved and solid phases in rivers and trace gases in the atmosphere. Areas of expertise include surface-water hydrology, major element and nutrient biogeochemistry, soil formation and sediment genesis, vegetation-landscape interaction, carbon-cycle characterization on land and in the ocean, and assessment of land-use and climate change. His work has included the study of natural and human-altered landscapes, in the Americas, Southeast Asia, and Africa, including large parts of the Amazon, Orinoco, Mississippi, and Panama Canal Basins and eastern Puerto Rico.
