Subject

My key research interest is to understand metabolism and regulation of microbial and mammalian cells in depth, thereby enabling model-based strain and process engineering finally to transfer novel bioprocesses from lab to industrial scale. As such, research activities are rooted in modern biochemical engineering closely following the mindset of systems metabolic engineering and also using tools of synthetic biology.
