I have about 15 years of experience in Fermentation technologies and Eco-Engineering of microbial consortia for the conversion of waste streams into biofuels, green chemicals and biopolymers, following a Biorefinery concept.My overall research interest is within the development of Defined Mixed Consortia and Process Optimization.  More in particular, I have a strong focus on the valorisation of crude glycerol into value-added products (i.e. biohydrogen, polyols, bioplastics), as well the biodegradation of recalcitrant compounds such as pesticides and plastics.
