His research focuses on the major processes controlling hydrogeochemical behaviors of Arsenic in the subsurface environment and the remediation of high arsenic aquifers. He also studies on the cycles on the speciation and mobility of Arsenic in the nature and under such anthropogenic activities. The research approach includes laboratory, field, and modeling studies of both natural and disturbed systems. He is an expert on the biogeochemical, hydrogeochemical and hydrogeological processes and the groundwater contamination.
