Areas of Interest

Areas of research interest are focused on innovative sustainable use of lignocellulosics. Specifically, we are seeking to develop new and improved applications for biomass, including biofuels and bioproducts, environmentally-friendly pulping and bleaching processes and recycled fiber. Achieving this goal requires research in several fundamental fields including lignin and carbohydrate chemistry, fiber characteristics, enzyme technologies and the use of sophisticated analytical tools.
