Investigations of large-scale biogas plants:

• Process monitoring
• Characterisation of mixing conditions in biogas reactors
• Development of an early warning system in terms of a process failure due to organic overloads etc.

Co-digestion: Optimisation of co-digestion in terms of

• specific biogas production
• product qualitiy
• integration in regional waste and wastewater management concepts

• 2006 - Diploma in Civil Engineering Technische Universität Berlin
