I am an economist with interest in political, public, crime and development economics. I work as Associate (tenured) Professor at University of Milan (Faculty of Law) and as Executive Director of the CLEAN Unit on the economics of crime at Bocconi University. I am also a Research Affiliate at CEPR and an Associate Researcher at the Institut d'Economia Barcelona.

My papers have appeared in (among others) the Economic Journal, the Review of Economics and Statistics, the Journal of Politics, the Journal of Development Economics, and the Journal of Public Economics. My book in Italian, Fallimento Lockdown, with Piero Stanig, was published in September 2021, and in the same year, has been among the best-selling books in the "political science" and "economics" categories on Amazon.it. ​

I have been involved in policy discussions on anti-corruption and organized crime, presenting my work at institutions such as the United Nations University, the European Commission, the Italian School of the Judiciary (Scuola Superiore della Magistratura), the Italian Senate, as well as to the heads of the Carabinieri and the Anti-Mafia Police in Italy. Each year, I lead master’s and PhD courses on corruption and crime-related topics, training top-level bureaucrats and law enforcement officials at the University of Milan.

​My research has been covered, among others, by The New York Magazine, The Guardian, The Telegraph, Courrier International, Corriere della Sera, La Repubblica, La Stampa. In Italy, I've written on Il Sole24ore, La Repubblica and LaVoce.info.
