Xuejun (Jun) Pan works to develop innovative technologies to produce fuels, chemicals, fibers, and other materials from lignocellulosic biomass. Specifically, Pan works on the following areas: (1) pretreatment and fractionation of lignocellulosic biomass; (2) enzymatic and chemical saccharification of lignocellulose; (3) chemical and biological conversion of lignocellulose to chemicals and liquid fuels; (4) high-value utilization of cellulose, hemicellulose and lignin; (5) fundamental understanding of physical and chemical changes of plant cell walls during biorefining.
