I am an Associate Professor (Docent) in Economic History at Lund University, Pro Futura Scientia Fellow XVI at the Swedish Collegium for Advanced Study (Uppsala University), a Research Fellow at the CEPR, and an Affiliated Researcher at IFN. Currently, I also serve on the editorial board of the Journal of Economic History and the European Review of Economic History. 


I am an economic historian interested in questions at the intersection of economic history, economic geography, and urban economics. My research employs historical big data and econometric methods to examine the forces shaping growth, innovation, and opportunity across cities and regions. A central theme of my work is understanding how policy interventions can alter spatial development trajectories and how technology shocks affect the fortunes of firms, individuals, and places in both the short and long run.


My research has been published in academic journals spanning economics, economic geography, economic history, general science, and sociology and has been widely featured in media outlets such as the BBC, CNN, the Economist, Financial Times, the Guardian, the New York Times, Scientific American, and Wall Street Journal, as well as being cited by organizations such as the World Bank and the WTO. I have also contributed expert advice on growth, technology, and regional development to the European Commission, the OECD, the Swedish Ministry of Enterprise and Innovation, and the United Nations. See CV for a full list of my professional activities and writing.
