I got my BSc in Electrical Engineering from
Michigan State University, then my Ph.D. in Mathematics from
Stanford University.
I spent some years of postdoc between the
CRM,
and the
Fields Institute in Toronto and PIMS at the
University of British Columbia
In 2000 I was appointed at the University of Lille1, and became a member of the
Laboratoire Painlevé (Unité Mixte de Recherche, UMR-CNRS 8524).
I am right now a faculy at the American University of Sharjah AUS
in the UAE.

My fields of mathematical research and interest are in
Algebraic Topology. 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.

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
