Research interests 

I am an applied economist specialising in agri-environmental economics (PhD Katholieke Universiteit Leuven). I have been involved as a consultant in policy-oriented projects on the economics of environment, agricultural trade and rural development for the World Bank, European Commission, FAO and OECD.
My main research interests are behavioural economics applied to food waste and recycling, land and water use, climate change, consumption of higher welfare and healthy food products, uptake of animal disease control technologies; economic modelling of the linkages between trade, animal health and welfare, and the environment; and analysis of environmental efficiency and efficiency of knowledge and innovation transfer.
