In my undergraduate studies I focused on ecology and the interactions between social and ecological systems. During this time I started to develop an interest in ecological economics and the relationship between the economic system and environmental and social challenges. I followed this interest by completing a Masters degree in ecological economics at the University of Leeds.

Currently, I am studying for a PhD in which I am investigating the macroeconomic implications of energy demand reductions and the role that sectoral shifts in the economy can play in reducing energy demand.

Project title

Shifting economic activity to low-energy sectors: Is it a viable strategy for post-growth economies?

Project outline

My PhD project is concerned with the relationship between energy use and macroeconomic dynamics. In general I am interested in the question how we can achieve significant reductions in energy use while maintaining an economy that delivers well-being for everyone. Using input-output analysis I am investigating specifically whether and how sectoral shifts in the economy can contribute to meeting that challenge.

Questions that I am exploring include: What could a low-energy economy look like? How have sectoral shifts in the UK economy impacted energy consumption in the UK? What is the differences in sectoral energy intensities in the UK and Germany when energy use along the supply chain is taken into account? How are measures of sectoral energy intensity related to labour productivity?
