My research interests include studying the fate and transport of inorganic contaminants in subsurface environments by using experimental and geochemical modeling tools. I have worked on developing a hybrid approach to modeling the adsorption of arsenic on natural sediments collected from a contaminated aquifer. The adsorption model was calibrated to the batch and column experimental data with the ultimate goal of being used in a reactive transport model to guide the in-situ remediation efforts.
