Specialty: Soil Microbiology

Research focus is on the physiological ecology of rhizobia under stress conditions including temperature, moisture, and acidity. Genetic diversity and population structure of indigenous Brady rhizobium species and rhizosphere bacteria are being studied using PCR, physiological activities via BIOLOG, and identification of bacterial communities in soil by pulse-field electrophoresis with restriction enzymes. Technology transfer projects involving biological nitrogen fixation are underway for developing countries and include evaluation of inoculant quality, inoculant production technology, and inoculant utilization. Also being studied are microbial ecology of nitrogen transformations in soils and aquatic ecosystems; microbial ecology of waste amended soils; and bioremediation of soils, especially those in fragile ecosystems, affected by heavy metals and pesticides.
