Our research goal is to develop processes that can efficiently convert cellulosic biomass into fuels and high value co-products. The approach is to develop technology for fractionating cellulosic biomass into component molecules and then use the most efficient processes to convert those into fuels and high value products. Specific areas of research include optimization of cellulosic pretreatments for ethanol production, modeling and optimization of integrated biorefineries, and novel separation methods for production of biofuels and bio-based chemicals.
