Most of our work over the last three decades has been directed towards applying chemical engineering thinking and principles including transport phenomena, chemistry and thermodynamics on processes in natural system. We have studied the release and fate of contaminants in soils and subsoils using field and laboratory experiment and modeling . We have studied metal release and transport from mine tailings, transport and microbially mediated degradation of organic contaminants from oil spills, radionuclide migration from final repositories to the biosphere, radon escape from rocks to buildings and may other phenomena. About 30 Ph.D. thesis have resulted so far.
