Research activity :
- Rheological behavior of fully formulated lubricants (oils, greases, emulsions, additives): characterization and modeling
- Relationship between lubricants composition & structure and their rheological & tribological behavior
- Film thickness and traction prediction in elastohydrodynamic (EHD) contacts by numerical modeling including non Newtonian approaches
