Office hours any time by previous appointment
In my research I am investigating the transformation process towards sustainable steelmaking. The goal of my research is to provide decision support for steel producers regarding the economically and ecologically beneficial design of transformation pathways. To this end, I use methods of activity analysis based modeling, mathematical optimization, and life cycle assessment. Thereby, I focus on the transformation of existing production networks in the steel industry.
