  • Areas of Interest

    Research; cell wall lignification of forages and mechanisms of cell wall digestion in the rumen.

  • Research

    Assigned responsibility is to improve forage utilization by dairy cows and as a resource for bioenergy production. Research is focused on understanding cell wall development and composition in alfalfa, perennial grasses, and corn stover/silage in order to identify targets for genetic modification that will increase digestibility by livestock and improve bioenergy conversion efficiency.
