Single-cell microbes, such as E. coli, P. putida and yeast, can be redesigned to be miniature chemical reactors that transform sugars and other carbon sources into biofuels and bioproducts. Researchers in the Pathway and Metabolic Engineering Group identify and introduce biosynthetic pathways from one organism into a host microbe, such as E. coli, P. putida and yeast, and then engineer metabolic pathways using genetic manipulation to optimize the production of target chemicals that the host microbe does not naturally generate in large quantity. We also explore chemical conversion of biomass-derived molecules to bioproducts and biofuels using heterogeneous catalysis to expand the scope of products and our capability of biomass conversion.

The goal is to characterize and discover metabolic diversity in nature, and create highly efficient, microbial factories for green, cost-effective and sustainable production of advanced biofuels and other valuable bioproducts. Potential biofuels and bioproducts candidates include fatty acid esters, alcohols, aromatics and isoprenoids.


  • Discovery of novel hydrocarbon biochemistries for novel bioproducts
  • Optimization of hydrocarbon biosynthetic pathways in selected hosts
  • Engineering of isoprenoid pathway for production of biofuels and bioproducts
  • Multi-Omics guided metabolic engineering
  • Chemical conversion of biosynthetic precursors to valuable products
  • Development and optimization of pathways for diesel-range methyl ketone biosynthesis
