PhD opportunity in Sustainable Aviation Fuels (SAF) at the University of Lorraine in Nancy, France, focused on the interface of chemistry , chemical engineering , and energy . The project investigates how SAFs age over time, how oxidation changes fuel composition, and how early oxidation products evolve into oligomers, gums, and deposits. The research combines reaction kinetics , analytical chemistry , spectroscopy , and process engineering to identify the macromolecules responsible for deposit formation and to measure their formation kinetics. Planned methods include experimental oxidation studies in reactors, GC/MS, HPLC, IR and Raman spectroscopy, and microfluidic approaches. The candidate will work on developing analytical protocols, characterizing oxidized products, and validating experimental methods for liquid-phase SAF oxidation. Eligibility highlights: applicants should have a master’s degree or engineering diploma in chemistry, chemical engineering, or a related area; strong motivation for multidisciplinary experimental research; good English skills; and an interest in analytical and kinetic studies. Experience with analytical methods is welcome. Funding details: this is a 3-year doctoral contract with a gross monthly salary of 2,135 EUR . Application window: the post indicates a September 2026 start in Nancy, France. The attached document says applications should be sent as a single PDF including a cover letter, CV, and academic transcripts in English to the listed supervisors.
