Hi! I am an Assistant Professor of Finance at the Faculty of Economics and Business (KU Leuven). My research focuses broadly on the introduction and adoption of new technologies by financial firms and their regulation. In particular, my findings support the design of policy actions seeking to reduce systemic risk and improve welfare and efficiency of financial services.

I am currently visiting scholar at the National Bank of Belgium. In the past, I was a visiting expert at the European Systemic Risk Board, a research consultant at a major European bank and a visiting scholar at the European Central Bank, the Deutsche Bundesbank and De Nederlandsche Bank. I was also research associate at the Massachusetts Institute of Technology (Media Lab) and visiting scholar at the University of Stanford (Economics), the University of Oxford (Said Business School) and the University of Cambridge (Isaac Newton Institute). I have a background in Engineering, Computer Science and Finance from the University of Brussels (B.Sc., M.Sc. and Ph.D.).
