Marjan De Mey obtained a PhD in Bioscience Engineering at Ghent University. She was visiting researcher at TU Delft (The Netherlands) and MIT (USA) and since 2011 she holds a position as professor in Metabolic Engineering at the faculty Bioscience Engineering of Ghent University where she leads the Metabolic Engineering group at the Centre for Synthetic Biology. Their research focuses on the development of novel tools and methods to fine tune metabolic pathways for the biosynthesis of chemically complex metabolites. These novel tools and technologies include several DNA parts libraries as well as efficient and rapid methods for constructing synthetic pathways, transferring them into prokaryotic or eukaryotic microbial systems, and screening them in a high-throughput manner. We apply these tools and methods to create custom designed microbes for the production of useful chemicals from renewable resources, in particular for the production of specialty carbohydrates and natural products. These molecules, or their direct precursors, have a myriad of high-added value applications in - among others- pharmaceuticals, food additives and cosmetics.
