John Ralph

Plants Lead

Ralph’s program is aimed at decreasing plant cell wall recalcitrance to processing and improving plant value to the biorefinery, largely by: detailing lignin structure, chemistry, and reactions; delineating the effects of perturbing lignin biosynthetic pathways; ‘redesigning’ lignins in planta to be more amenable to depolymerization; and delineating plant cell wall cross-linking mechanisms. To pursue these goals the group develops synthetic methods for biosynthetic metabolites, precursors, intermediates, molecular markers, and cell wall model compounds, as well as analytical and visualization tools to probe structure, reactivity, and cell wall processes.
