Biological and Catalytic Conversion of Sugars and Lignin
Our research group—composed of staff scientists, postdoctoral associates, students, and technicians—develops biological and chemical catalysts for cost-effective production of fuels and chemicals from terrestrial biomass.
An NREL study of cellulose translocation in the bacterial cellulose synthase predicts how cellulose is synthesized in its cellobiose form.
Our team published a study on using base-catalyzed depolymerization on several biorefinery-relevant lignins, which was selected as an ACS Editor's Choice article at ACS Sustainable Chemistry and Engineering.
A study about fungal cellulases was published in Chemical Reviews with collaborators at Swedish University of Agricultural Sciences, which is serving as a useful resource for the cellulose community.
Lignin Valorization
Our group is pursuing strategies to depolymerize lignin in an integrated biorefinery context and subsequently upgrade lignin-derived aromatics into value-added chemicals to realize a more holistic, integrated approach to biomass conversion.
Biological Upgrading of Sugars
Our group focuses on biological upgrading of some of the most commonly sought products from lignocellulosic biomass, pentose, and hexose sugars trapped inside the polysaccharides, to fuel precursors and value-added chemicals.
Chemical Catalysis and Separations for Fuels and Chemicals Production
We are developing bench-scale catalytic and separations processes to produce hydrocarbon fuels and value-added co-products from biologically and catalytically derived intermediates from biomass.
Enzymology
Our group has a keen interest in the development of molecular insights into enzymatic processes for both deconstructing cellulose and also assembling it as well as in the use of novel metabolic enzymes for biologically producing fuel precursors.
