Anaerobic microbial communities play a central role in the treatment of organic wastes and the recovery of valuable products from waste streams. Understanding and controlling these complex communities is therefore critical for developing more efficient and sustainable environmental biotechnologies. Our research group studies the microorganisms, metabolic pathways, and community interactions that govern anaerobic conversion processes. We seek to link microbial community structure and function with reactor performance and to develop strategies for steering metabolism toward desired products. We are particularly interested in anaerobic digestion, resource recovery, and the production of value-added chemicals from waste.
