I am interested in the distribution of people and economic activity in space and its relationship with economic development. I am a pluralist when it comes to theory and empirics, as long as space is involved.

I work as Regional Inequalities and Demographic Change Programme Manager at the OECD. I am also an  Honorary Associate at the Geography and Planning Department at the University of Liverpool. For a full list of articles see my Google Scholar page.
