Research Areas

Dr. Wyman's research targets biological conversion of abundant, non-food sources of cellulosic biomass to commodity products including ethanol for use as a transportation fuel, an area on which he has focused almost exclusively since 1980, with emphasis on pretreatment and enzymatic hydrolysis. e He has long believed that biomass is the most economical way to store solar energy, biofuels present the only sustainable option to reduce our petroleum dependence for liquid transportation fuels on a large scale, and modern biotechnology will dramatically reduce costs of making cost-competitive fuels and chemicals from biomass with tremendous environmental, economic, and strategic benefits. Thus, a substantial portion of our research is directed at experiments and modeling to enhance our knowledge of the most expensive and critical unit operations for biological conversion of cellulosic biomass to ethanol and other products: pretreatment and cellulose and hemicellulose hydrolysis. In addition, a second element focuses on the design of systems for converting biomass into fuels and chemicals with the goal of identifying opportunities to advance technology and substantially reduce costs. A third element applies life cycle analyses and other tools to better understand the environmental and societal impacts and benefits of converting biomass to fuels and chemicals and help us identify process configurations with even more favorable features as well as define policies to accelerate use of beneficial processes.
