个人简介

Current research focuses on the production of bio-fuels and value added chemicals through biochemical conversion processes. The research is highly interdisciplinary and there are occasional openings for new graduate students.

研究领域

Biomass Pretreatment Thermal, chemical (ionic liquids), mechanical and biological pre-treatment methods for lignocellulosic biomass are investigated. Effects of potential fermentation inhibitors are quantified in miniaturized high-throughput experiments. Ethanol and Butanol Fermentation Research focuses on in-situ product removal and process compression, as well as on reactor design and mathematical modeling. Scale related work investigate key process parameters from micro-scale, via bench-scale to pilot-scale. Micro-Algae Cultivation Genetic tools are being developed to enhance the production of high value chemicals in micro-algae. Additional work investigates ionic liquid-based lipid extraction and the continuous CO2 to lipid conversion for biodiesel production. Recombinant Protein Production Therapeutic proteins are being expressed in insect cells through the Baculovirus system. Protein purification and downstream processing is a secondary research focus. Bioassay Development for Emerging Contaminants Various bioassays for the quantification of genotoxicity and estrogenicity of micro-pollutants and their degradation products are being investigated in this cluster.
