Engineering microbiology often relies on pseudo-theory in the development of descriptive and design tools; however, such methods rarely describe real systems with consistancy. Our work combines methods from engineering, theoretical ecology, mathematics, biochemistry, and molecular biology to solve problems in environmental engineering at a fundamental level. Research topics include biological waste treatment, ecotoxicology, bioremediation, and the environmental fate and impacts of trace and genetic contaminants. Current research projects includes 1) the transmisson, fate and impact of antibiotic resistance genes in the environment resulting from human activity; 2) energy minimization in water, wastewater and solid waste management systems; 3) the microbiology and ecology of greenhouse gas suppression and productiuon in geochemical settings, especially in Polar regions; and 4) water and environmental quality in the developing and emerging world.
