My research contributes in addressing the important question of how to design sustainable agricultural and agri-food systems that ensure supply of food, fibre and biomass and enhance agri-ecological processes within a changing socio-economic and bio-physical environment. I develop and use generic quantitative methods and decision support tools that are able to systematically evaluate the consequences of important drivers of change. My previous and ongoing research revolves around three main topics i.e. (i) Integrated Assessment of agricultural and environmental policies, (ii) climate change and scenario studies and (iii) exploration of alternative production options in agri-food production chains. My future research aims to span the bridge between OR models that analyse decision making in production and procurement of agricultural raw materials and decision support systems of the agri-food supply chains.
