Our group develops green processes and green products using the tools of biology, chemistry, chemical engineering, and material science. Specifically, we focus on ways to improve lignocellulosic biomass conversion and in the area of plastics upcycling. We develop strategies and holistic processes that combine biological and chemical transformations to upcycle both low-value biomass components, such as lignin, and waste plastics such as polyethylene terephthalate, polyolefins, or other recalcitrant waste polymers into higher-value chemicals and materials. Our group combines expertise in metabolic engineering, synthetic biology, bioprocess development, separations, homogeneous and heterogeneous catalysis, polymer synthesis and characterization, computational chemistry, molecular simulation, and process analysis.
