IFPEN regularly hosts renowned external researchers, for periods ranging from a few months to a year, as well as outside PhD students on a temporary basis.


Researcher exchanges take place within the framework of collective research activities and a spirit of openness to the outside world. The presence of visiting researchers provides a platform for comparison and exchange. IFPEN researchers are also able to spend several months conducting research in a partner laboratory. Such exchanges are particularly beneficial for both sides, providing food for thought for researchers and contributing to research advances. 

Would you like to spend time working with IFPEN’s teams?
Do not hesitate to discuss your ideas with IFPEN researchers during projects, conferences or other events.  

By way of example, in April 2020, IFPEN’s Geosciences Division welcomed Doctor David Sebag for one year. Specializing in Environmental Geosciences,  he has joined the team to reinforce its Soil Science expertise and will tackle different themes :

  • the construction of a database and standardization of procedures for studying soils,
  • the development of new Rock-Eval® approaches to characterize carbon forms in soils,
  • and the study of carbon stabilization, sequestration and storage processes in soils related to pedoclimatic conditions, land use and agricultural practices.


This form of hosting applies to a student enrolled as a PhD student in a French or foreign university, with no connection to IFPEN, who is temporarily hosted at IFPEN during his/her thesis. The visiting student is hosted for a period of between three and six months.
