Dr. Vasudevan's research is concerned with the fate of synthetic and naturally occurring organic and inorganic compounds. Her work focuses on the mechanisms by which organic and inorganic compounds interact with mineral surfaces in soil and aquatic environments. Central research issues include the study of sorption, desorption and coordination chemistry; surface complexation theory; mineral precipitation, dissolution, and weathering; and surface-assisted chemical transformation processes. Dr. Vasudevan and her group use a combination of controlled laboratory experiments, molecular and surface complexation modeling, and statistical tools in their research. Completed and current projects have emphasized the study of iron oxide rich soils, and pure phase minerals (iron, aluminum and titanium oxides, silica, and kaolinite) and include:
