About me

I am a postdoc at the University of Bremen since September 2024 hosted by Prof. Dr. Nicole Megow. Before this I worked as a postdoc at the Technical University of Munich hosted by Prof. Dr. Andreas Wiese and obtained my PhD at Maastricht University supervised by Prof. Dr. Tjark Vredeveld and Dr. ir. Tim Oosterwijk.
