My research focuses on modelling of coupled multiphysics phenomena applied to materials engineering, fluid/solid mechanics and process simulation.
The aim of my research is the development of robust mathematical models and numerical tools (i.e. MultiScale and Stabilized finite Element Method) for modelling/understanding direct elaboration processes and the resulting structures / microstructures.

Teaching
Teachings were given from the beginning of my PhD thesis for 1st year, 2nd year and 3rd year students of the Ecole des Mines de Saint-Étienne. Courses for 3rd year students are also for M.Sc. level. The topics of courses and tutorials deal with mechanics, computational mechanics and finite element methods.
