Dr. H Madgi Selim is professor of Soil Physics at Louisiana State University in Baton Rouge. Dr. Selim's research accomplishments have been in the areas of solute and water flow in unsaturated and saturated soils, water management of irrigation and drainage systems, spatial and temporal variability of soil physical properties, and chemical and physical processes governing the interactions and transport of solutes in the root zone. Selim's research emphasizes the role of slow heavy metals release and processes governing mechanism of heavy metals in the vadose zone.
