A fully funded PhD position is available at the University de Lorraine (Archives Henri Poincaré, Nancy, France) in the philosophy of science, focusing on explanatory progress and degrees of understanding in mathematical and mathematized sciences. The doctoral research will investigate how explanations and understanding of scientific phenomena can be gradably improved, especially when these phenomena are described by established theories, laws, or models and explored using mathematical methods. Case studies are expected to be drawn from physics, with strong connections to the literature on scientific explanation and understanding. Cross-comparisons with mathematics are also encouraged.

The successful candidate will join the GRASP project (“Gradability across Science and Epistemic Practices”), funded by the ANR, and benefit from a vibrant international research environment. The project brings together philosophers of science, epistemologists, and philosophers of mathematics and physics. Supervision will be provided by Cyrille Imbert (Université de Lorraine) and Vincent Ardourel (Université Paris 1 Panthéon-Sorbonne), with co-supervision arrangements allowing the student to benefit from both institutions' research environments.

The position is fully funded for three years, with a gross monthly salary of 2300 € (approx. 1920 € net), including social security, pension, and unemployment benefits. No teaching is required, but optional teaching activities are available. The PhD will be based at the Archives Poincaré, a renowned research institute in philosophy of science and mathematics, and will involve regular interaction with the GRASP project team and international collaborators.

Applicants must have a MA in Philosophy with training in philosophy of science and epistemology. Additional scientific qualifications are an asset. Good English proficiency (B2 or higher) is required; French is not mandatory but candidates are expected to develop fluency during the PhD. Application materials include a CV, cover letter, transcripts, recommendation letters, English proficiency certificate, two writing samples, and a research proposal aligned with the project. The application deadline is April 10, 2026. For more information and updates, consult the CNRS job portal and project links.
