Fascinating work on how the Italian Mafia has penetrated countries in Africa, from a group including Stefano Gurciullo, a researcher who I co-supervise as a PhD student in Political Science and Computer Science at UCL. This builds on Stefanos past work using social network analysis to examine the Mafia's penetration of businesses in his homeland of Sicily. Stefano's PhD project (with his primary supervisor Slava Mikhaylov) is on new models of how economic shocks affect the stability of the international banking system, and is in collaboration with researchers at The Bank of England.I'm very lucky to have such fascinating and brave students to work with!
