Youssef Azouzi

Researcher at IPEST, University of Carthage and member of the LATAO LR11ES12 research laboratory, his research focuses on probability theory in ordered spaces. Lately, he has been interested in Banach lattices and in applications of ordered spaces to finance and economics. He is also interested in operator theory and has collaborated with researchers in Europe (ICMAT Madrid) and Africa (Wits University, South Africa).
