Dr. Ren directs the Bioenergy and Bioresource Reccovery Lab in Environmental Engineering at the University of Colorado Boulder. His research focuses on energy and resource recovery during waste treatment processes, with the goal of expanding environmental engineering from pollution clean-up to sustainable development of energy and environmental systems.
The Ren lab uses microbial and electrochemical systems to directly convert biodegradable materials, such as wastewater, biomass, and MSW into hydrogen gas, electricity, and other value-added commodity chemicals, and they use molecular microbiology tools and electrochemical analyses to understand the fundamental determinant factors of those systems so as to enhance design, operation, and monitoring in concert with traditional approaches.
The Ren lab always welcomes motivated students, postdocs, and visiting scholars to join our energetic team. Please contact Dr. Ren for any questions.
