PhD in Physics of Advanced Materials – Polymer Crystallization and Recycled PET University of Luxembourg in Luxembourg

The University of Luxembourg’s Faculty of Science, Technology and Medicine (FSTM) is seeking a highly motivated PhD candidate to join the Research Group Physics of Advanced Materials. This position, supervised by Dr. Jörg Baller, offers a unique opportunity to conduct advanced research in experimental physics and materials science, with a particular focus on the crystallization and processing of recycled PET (Polyethylene Terephthalate) polymers.

The research project is part of a joint initiative between the University of Luxembourg and a local international company, with 50% of the candidate’s time spent at each institution. The project aims to advance sustainability by investigating the physical processes involved in the processing of recycled polymers. Research topics include the crystallization of polymers, analysis of semi-crystalline polymer structures, and the study of mechanical and thermal properties. The work will involve laboratory experiments, data acquisition, validation of findings, publication of results, and participation in workshops.

Candidates should hold an MSc in Physics, Engineering, or Chemistry, and have familiarity with design-of-experiments, soft matter physics, and programming (e.g., Python). Experience in X-ray scattering, rheology, or thermal analysis is considered a plus. Strong English language skills are required, and knowledge of German, French, or Luxembourgish is advantageous. The position is ideal for candidates passionate about multidisciplinary research and eager to work in a dynamic, international environment.

The successful applicant will benefit from the University’s modern infrastructure, high-quality equipment, and close ties to industry and European institutions. The position is funded through the Luxembourg National Research Fund’s Industrial Fellowship program, with a yearly gross salary of EUR 40,952. The contract is for 36 months, extendable up to 48 months if required.

Applications should be submitted online via the University of Luxembourg HR system and must include a CV, cover letter, thesis and publication list (if available), transcripts, and contact details for two references. Early applications are encouraged as review will begin upon receipt. The University of Luxembourg is committed to diversity and inclusion, welcoming applicants from all backgrounds.
