The role of microorganisms in soil and engineered systems. Risks associated with microorganisms in organic waste streams, antibiotic resistance in the environment, and bioremediation of harmful substances.
Research: 1) fungal and bacterial degradation of chlorinated solvents, pesticides, cyanotoxins and oil in the environment; 2) bacterial antibiotic resistance in rivers; 3) plant-microbe interactions in agriculture; 4) circular organic waste streams; 5) mycorrhizal fungi and plant nutrition.
