My research is concentrated in two areas, agrogeology and environmental geology. The agrogeological research and development for tropical countries focuses on the use of locally available minerals and rocks to enhance soil productivity. Collaborative applied research projects in modification and utilization of phosphate rocks and rock fertilizers are currently underway with partners in Kenya, Uganda, Tanzania and Zambia as well as in Brazil and Indonesia. The main thrust of this research is to develop appropriate and economic techniques to enhance nutrient release from minerals and rocks. Research in environmental geology centres on health-related geochemistry and industrial mineral (phosphates, zeolites, vermiculites, etc) and organic 'wastes' as potential 'resources'.
