About the FSTM

The University of Luxembourg is an international research university with a distinctly multilingual and interdisciplinary character.

The Faculty of Science, Technology and Medicine (FSTM) at the University of Luxembourg contributes multidisciplinary expertise in the fields of Mathematics, Physics, Engineering, Computer Science, Life Sciences and Medicine.
Through its dual mission of teaching and research, the FSTM seeks to generate and disseminate knowledge and train new generations of responsible citizens in order to better understand, explain and advance society and environment we live in. 

Your role

The PhD candidate will generate and study complex macroscopic flow patterns of LCE precursors, polymerize the precursors into LCEs programmed by the flow patterns, and study the resulting actuation behavior. You will be working practically in the lab using commercial rheometers, mechanical testers, polarizing microscopes etc., in addition to bespoke equipment built for establishing the controlled flow at tunable temperature and photopolymerization of the precursor. The practical work will be complemented by fluid mechanics computer simulations, including solutions employing machine learning, and theoretical analysis using Leslie-Ericksen theory for liquid crystal flow as well as theory for viscoelasticity of polymeric liquids. Both in the practical and simulation/theory work you will be guided and supported by post-docs and senior researchers, in Luxembourg and from our international network of collaborators. You will be spending time also in Cambridge and Lisbon.

Your profile

The PhD candidate must have a strong physics background, with good understanding of continuum/fluid mechanics as well as polarizing optics. Experience with liquid crystals and polymeric liquids is a strong asset. An M.Sc. in physics is ideal, but also materials science, mechanics or chemistry M.Sc. may be adequate if the candidate shows strong interest and good understanding in physics (short-listed candidates will be tested for this during interviews). We expect strong capacity for critical thinking and excellent research ethics. The person must posses fluent written and verbal communication skills in English.

How to apply

Applications should include:

  • Curriculum Vitae
  • Cover letter - Explain your motivation for pursuing a Ph.D. and why the Experimental Soft Matter Physics group aligns with your career goals. While AI can help with language correction, we discourage using it to write the letter itself, as this may result in a less authentic and personalized application

  • PDF version of your PhD thesis

Early application is highly encouraged, as the applications will be processed upon reception. To ensure full consideration, candidates should apply by 30th of July 2025 ONLINE formally through the HR system. Applications by Email will not be considered.

All qualified individuals are encouraged to apply. In line with our values, the University of Luxembourg promotes an inclusive culture. We encourage applications from individuals of all backgrounds and are dedicated to upholding equality and respect for our employees and students.
