Director of Microbial Communities

Research Focus

Understanding how microbial communities deconstruct and metabolize lignocellulose and identify the genes, pumps and proteins responsible for this activity.


  • Thermophilic microbial consortia that produce highly effective enzymatic mixture for high temperature biomass deconstruction
  • Identification of mechanisms and pathways for depolymerization and bioconversion of lignin
  • Understanding mechanisms of ionic liquid tolerance in bacteria and fungi
  • Improving enzyme production in thermophilic fungi (with Pacific Northwest National Laboratory)
  • Clostridium thermocellum hydrogen production in the presence of biologically-based ionic liquids (with National Renewable Energy Laboratory)
