Query: Mechanical behavior of steels: from fundamental mechanisms to
  macroscopic deformation   My scientific activities aim at understand and predict the mechanical
behaviour of steels, from fundamental mechanisms to macroscopic deformation.
This manuscript is dedicated to the TWIP effect (TWinning Induced Plasticity)
of high manganese austenitic steels and DP effect (Dual-Phase) in more
conventional Ferrite-Martensite steels.
