Description :
Located in Lyon area, Research center of Solaize (CRES) of TOTAL Marketing & Services have strong skills dedicated to lubricants, fuels, bitumen and specials fluids research field. CReS push up new class of products, disruptive materials with enhanced valuable impact required by our customers.

In the framework of bituminous binders area, Bitumen research team is in charge of new bitumen and specialities developments, characterization methods and fundamental investigations for upgrading our knowledges.

In road pavement, bitumen emulsion (oil-in-water)is used for cold mix asphalt technology for laying. However, bitumen abilities for emulsion have to be handling with precaution and deeper understanding of bitumen matrix interfacial properties have to be improved as well as its emulsion behavior.

The work will investigate and validate latest research experiments and methods developped in case of crude oils emulsion. The interest is to combine advanced analytical separative sciences and physical chemistry characterization methods and interfacial rheology to overcome complex petroleum matrix analysis as bitumen.

The candidate will be based at UPPA - Pau with possible stays at the TOTAL Research Center in Solaize, close to Lyon.
He/She will work under the supervision of Pr Christophe Dicharry/Dr Patrick Bouriat at the Laboratoire des Fluides Complexes et leur Réservoir (LFC-R) of UPPA/CNRS/TOTAL (UMR 5150), as a member of Interfaces and Dispersed Systems Research team.

This project will be conducted in close cooperation between the laboratory and different R&D teams of TOTAL.

Application profile :
PhD in physical chemistry and Interfaces, colloïd systems, rheolofy of dispersed systems.
Good knowledge of physical-chemistry and Interfaces, dispersed systems.
1rst experience in petroleum matrix or interfacial rheology will be a real plus.
Strong interest for experiments and method developments
