Faculty Overview

Dr. Zheng is interested in the development of advanced biotechnologies and bioprocesses for converting biomass into renewable biofuels and bio-based products while protecting the environment and conserving our natural resources. The biomass includes dedicated crops, algae, agricultural residuals, food processing wastes, and municipal solid waste. Dr. Zheng’s research focus is on feedstock handling (e.g., storage and pretreatment) and bioprocess engineering to produce multiple biofuels (i.e., biogas, biodiesel, bioethanol, and liquid hydrocarbon) and bio-products (i.e., bio-based adhesive, unsaturated fatty acids, and film). In order to address the challenges of bioconversion of biomass, especially lignocellulosic biomass, Dr. Zheng is also interested in the integration of chemical catalysis with bioprocesses to improve the efficiency of biomass conversion and reduce the cost. His current research is in the areas of:

  • Anaerobic digestion for biogas production
  • Algae-based fuels and bio-products
  • Enzymatic catalysis and microbial fermentation
  • Lignocellulosic biomass pretreatment
