This research is aimed at a better understanding of biochemical, ecological and physiological functioning of soil and environmental microorganisms. The goal is to develop fundamental knowledge and apply the information obtained to the management for sustaining agricultural production and preserving natural environment. Current research emphasis is on soil carbon and nitrogen sequestration, soil nitrogen transformation kinetics, and microbial community structure and function.
