Paul Jorion is, since March 1, 2016, Associate Professor of the Faculties of the Catholic University of Lille. He is a financial columnist for L’Écho and Trends-Tendances, also for the literary magazine Quinzaines. He was a member of the High Committee for the Future of the Belgian Financial Sector and of the Reflection Group on the Positive Economy led by Jacques Attali. He graduated in sociology and social anthropology (PhD in Social Sciences from the Université Libre de Bruxelles): he was the student in Paris of Claude Lévi-Strauss (Collège de France) and the mathematician Georges-Théodule Guilbaud (École Pratique des Hautes Études) and in Cambridge of Meyer Fortes and Sir Edmund Leach, both students of Bronislaw Malinowski, the founding father of British social anthropology. He also trained as a psychoanalyst with the Jesuit psychoanalyst and philosopher Philippe Julien.
Jorion taught social anthropology at the universities of Brussels (1977/79), Cambridge (1979/84), and at the University of California at Irvine where he was Regents Lecturer (1997), and at Paris VIII (1985/86) where he taught psychoanalysis. He solved at that time, in collaboration with Sir Edmund Leach and two mathematicians (Elaine Lally and Gisèle De Meur), two enigmas in kinship algebra: the cases of the Pende of Kasai (DRC) and of the Australian Murngin.
Jorion was also a United Nations (FAO) official involved in development projects in Africa (1984/87). He was a researcher and developer in Artificial Intelligence as a member of the British Telecom Connex project (1987/90), during which he developed the ANELLA software (Associative Network with Emergent Logical and Learning Abilities) whose originality resided in a memory model animated by an emotional dynamics operating on a universe of lexicon words, in a perspective inspired by his psychoanalytical training.
Jorion worked (1998/2007) in the US banking industry as a pricing specialist. He had previously traded futures in a French bank (1990/91). He has published a book in English on the impact of the Enron bankruptcy on the stock markets: Investing in a Post-Enron World (McGraw-Hill 2003). He played a pioneering role in the development of high frequency trading (at the Bank of the European Union in Paris, then at Frontier & Cos. in Houston, Texas), as well as the development of the e-MITS software, a fully automated home loan allocation system for the Californian bank IndyMac (1998/2002).
