Areas of Expertise

Eric. P. Knoshaug works in the Applied Biology Section of the National Bioenergy Center at the National Renewable Energy Laboratory (NREL). He joined NREL in August 2000 and has since worked on engineering yeast for efficient utilization of biomass-generated pentose sugars, protein design and evolution for increased activity on recalcitrant biomass substrates, and increasing biomass and lipid production in microalgae.
