Research has emphasized environmental fate of xenobiotic compounds, elucidating biochemical pathways for xenobiotic metabolism, and factors affecting degradation in terrestrial and subsurface environments. The significance of the research is to gain knowledge leading to the development of biologically mediated preventative and remedial measures for control of surface and subsurface contamination. Present research focuses on factors controlling the fate of pesticides and nutrients in the environment, phytoremediation of organic contaminants, and measures for regulating the availability of pesticides for transport.
