1. At least two lectures in the field of microbiology (for a selection see the course catalog at the university portal).

• Systematic of the Prokaryotes (winter semester)
• Gene regulation in Prokaryotes (winter semester)
• Synthetic and Applied Microbiology (winter semester)

?

2. One seminar in the field of microbiology (for a selection see the course catalog at the university portal).
