Metabolism is the ‘engine’ of microbial live, generating energy and redox equivalents but also precursors for growth. Its sustained operation by large networks of enzymatic reactions forms a complex network that requires fine-tuned regulation. Malfunction of the regulation can lead to accumulation of intermediates and loss of function and decreased fitness (or even death). The network stoichiometry has been studied intensively including the use of metabolic tracer experiments to quantify steady-state fluxes of the network. Identifying the underlying kinetics and understanding the regulatory mechanism of metabolism is the aim of the Wahl group. These insights are then used to design microbial cell factories that operate robust under industrial conditions.

Current projects


The courses I teach cover different aspects of the Life Science and Technology (LST) curriculum as well as post master education (Biotechnology Academy Delft)

I believe that following elements are indispensable for an effective and fun course

  • Clear and transparent structure of the content and the grading scheme
  • Elements of competition
  • Early and sufficient feedback on student activities
  • Appreciate and motivate student activity

The content has to stimulate thinking and challenge students. Therefore relevant and challenging assignments are central in my courses. I use group-work to stimulate peer learning. Extensive support and feedback are used to further improve the quality.

For the preparation, communication and execution of course concepts, gamification is applied. The concept values all student’s activities and motivates for active participation. A list of current courses can be found under ‘Teaching’.
