Luc Dormieux is a professor at the Ecole Nationale des Ponts
et Chaussees, specialising in the mechanics of porous environments.
In 2002 he edited a special issue of the Journal of Engineering
Mechanics, and is about to publish (16/10/2005) a book joint-edited
with Franz-Josef Ulm entitled "Applied Micromechanics of
Porous Materials", to be part of Springer-Verlag's CISM
International Centre for Mechanical Sciences Series.

Djimedo Kondo is a professor at the Lille University of
Science and Technology, specialising in the mechanical reliability
of materials and structures & geomechanics. He has authored
over 20 journal papers.

Franz-Josef Ulm is an associate professor at the
Massachusetts Institute of Technology. He specialises in the
durability mechanics of engineering materials and structures,
computational mechanics, bio-chemo-poromechanics, & high
performance composite materials. He sits on the editorial board of
the Journal of Engineering Mechanics. He has recently co-authored a
book with Luc Dormieux (see above) and co-authored the 2 volume
"Mechanics and Durability of Solids" with Olivier
Coussy in 2001.
