Michaela Rohrbach

Michaela Rohrbach has been a research scientist at ISOE since January 2018. She studied climate change adaptation (Water Management) and Urban Environmental Management in the Netherlands. During her master thesis, she investigated the possibility of combining decentralised wastewater technologies with urban agriculture within a building complex by means of material flow analyses.

Focus of research
