Hi! I am an Assistant Professor of Finance at the Faculty of Economics and Business (KU Leuven). My research focuses on the interactions between financial markets, new technologies and policy. As such, I am interested in (i) how new technologies transform (or not!) financial interactions and (ii) how financial constraints condition the development of new technologies.
NEW! My policy report to the European Commission on the policy challenges and opportunities of Decentralised Finance (DeFi) is available → here
