David was educated at the TU Berlin and has a scientific background in bioprocess development, modelling and optimization. As a PhD student he investigates the impact of the lignocellulosic raw material characteristics on simultaneous saccharification and co-fermentations (SSCF) for bioethanol production. With modelling techniques he develops a framework based on sub-models of the bioethanol process to reveal the impact of raw materials on cell and process conditions. The developed sub-process models are used for optimization and control of SSCF processes. Furthermore, different process configurations are tested to improve ethanol yields and the overall robustness of the process.
