Curriculum Vitae	I got my BSc in Electrical Engineering from Michigan State University, then my Ph.D. in Mathematics from Stanford University. I spent two years at the Centre de Recherche Mathematiques at Montreal, then one semester at the Fields Institute in Toronto. I was afterwards lecturer at the University of British Columbia and Postdoctoral fellow at the newly constituted Pacific Institute for the Mathematical Sciences. At the moment I am a Faculty at the University of Lille1, and a member of the Laboratoire Painlevé (Unité Mixte de Recherche, UMR-CNRS 8524). I was born and raised in Tunisia
Affiliations	Founding Member of the Southern Mediterranean University in Tunis. Member of the Groupement de Recherche GDR 2875, Topologie Algébrique et Applications. Membre du GGTM (Groupement de topologie et de géométrie du Maghreb). I've been in 2009 a CNRS research associate (i.e. délégation CNRS auprès du PIMS). I am currently a visiting Professor at the American University of Sharjah, UAE.
Research Area	My fields of mathematical research and interest are in Algebraic Topology (string topology, homotopy theory, manifold theory) and in classical Algebraic Geometry (Riemann surfaces). Recent research involves studying spaces of configurations on manifolds and their analogs; like permutation products, finite subset spaces and barycenter spaces. A common thread in much of my research is the topology of function spaces like loop spaces, holomorphic mapping spaces and spaces of embeddings. These are topics with applications to homotopy theory, mathematical physics (gauge theory, sigma models), non-linear analysis (problems of N-body type) and moduli spaces. Nice and instructive links about my area of research can be found here What is Algebraic Topology Cent ans de Topologie Algebrique Mathematicians on Mathematics and its Beauty
Other Interests	I have a strong interest in urban planning and in environment protection (mostly pertaining to Tunisia). I write newspaper articles from time to time. You can read me here Member of Alyssa Network here
