About Me

I am an ETH environmental engineer and former PhD student in the Process Engineering department of Eawag under the supervision of Prof. Kai Udert. In my PhD project, I focused on optimizing nutrient recovery from urine for Space Missions. I am interested in modelling, decentralized waste water treatment, source separation, nutrient recovery and closed-loop systems.
