Bioeconomy, Life Cycle Assessment (LCA), Renewable Energy Systems, Agro-Ecology




I use data to help stakeholders make informed investment choices with regards to the long-term environmental consequences of different options, typically related to biomass use. My field of research lies at the crossroads of bioeconomy, circular economy & renewable energy systems, in the transition towards a decarbonized economy. It endeavours to identify synergies between these areas in an effort to achieve a high degree of system efficiency, minimize environmental impacts as well as the use of fossil carbon. In other words, I strive to re-think how we supply food, energy & chemicals to the World, as well as how we manage waste. Life Cycle Assessment, Energy System Analysis & Spatial Analysis (GIS) are the key analytical tools I apply and develop in my research.
