My basic research focuses on steel and steel recycling in global value chains. I am the principal investigator of the project »Techno-Economic Analysis of Steel Recycling« (TEASR), funded by the Carl-Zeiss-Stiftung. The project investigates the availability of steel scrap as a raw material for recycling in Europe. It considers the principle availability of scrap in Europe as well as the practical availability considering prices and trade flows.
 

More broadly, I analyse energy intensive industries as well as material and energy demand along global value chains. To this end, I employ input-output techniques, decomposition analyses, and general equilibrium models grounded in trade theory.  In my research, I study the connection between final demand and material as well as energy along global value chains. In other words: How does an increase in demand for cars in China affect copper mining in Chile?

​

I have contributed to studies combining input-output methods with demand system estimations to quantify household-level heterogeneity in material use and greenhouse gas footprints. Furthermore, I have developed and applied trade-theory based general equilibrium models to study phenomena ranging from climate policy to regulating the use of sand in South-East Asia.

Applying methods to analyze global value chains, my applied research focuses on steel recycling, the steel industry, and the automotive sector. I conceptualized and quantified the scrap bonus, the societal benefits of steel recycling as well as developed policy options to internalize these benefits into the price mechanism. My work defined and quantified the steel
intensity of consumption, an indicator measuring the amount of steel required by households’ consumption. I have contributed to projects studying the future of the automotive sector in Europe.
