Expertise and Research Interests

My research interests are focused on the roles of maintaining the productivity of soil, and in maintaining environmental quality. My research expertise covers a broad spectrum ranging from the applied management of leguminous crops, measuring the processof dinitrogen fixation under field and laboratory conditions, the population ecology of rhizobia in soil, and the physiology of bacteria under laboratory and field conditions. Currently, my research is focused upon the role of ammonia-oxidizing bacteria in biodegrading fumigants and aliphatic halogenated hydrocarbons that are priority pollutants. In addition, interactive research is being conducted with hydrologists to examine the interaction between water movement and microbial activity upon breakdown ofpollutants in the subsurface environment.
