MSCA Postdoctoral Fellowship: Apply with IMT Atlantique and join us!

Thinking about your next career step and willing to boost your career? Looking to experience intersectoral, interdisciplinary and international research? Wishing to carry out your research in a place addressing industrial, environmental, societal and digital transitions as a priority challenge?

Then apply for a Marie Sklodowska-Curie (MSCA) Postdoctoral Fellowship with IMT Atlantique as your host institution!

The MSCA Postdoctoral Fellowships (PF) provide funding to promising postdoctoral researchers with a view to develop their academic and transferable skills and enhance their career prospects by moving and working abroad.

By applying with IMT Atlantique you give yourself a chance to join a technological university ranked among the top 500 universities in the world according to the Times Higher Education (THE) World University's 2026 ranking (top 301-400 for Computer Science, top 201-250 for Engineering, top 301-400 for Physical sciences, and the 124th in the 2026 THE Interdisciplinary Science ranking, and top 51-100 for Data Science and Artificial Intelligence in the 2025 Shangaï ranking. IMT Atlantique is also awarded with the “Bienvenue en France” label, a recognition delivered by Campus France for our capacity to welcome and host international researchers in the best working conditions.

Topic open:

Neutron stars (and their mergers), the early universe, and heavy-ion collisions all provide complementary views on the behavior of quantum chromodynamics (QCD) matter under extreme conditions of density and temperature. Here, matter exists in the form of the quark-gluon plasma (QGP) or of quark matter. The understanding of its equilibrium and transport properties, as well as its more exotic phases, is of utmost importance when it comes to fundamental questions about the evolution of the early universe and compact stars. How does the quark-hadron phase transition impact the emission of post-inflationary gravitational waves? What do binary mergers reveal about the core of neutron stars? Heavy-ion collisions at facilities like the LHC and RHIC recreate these extreme environments and allow us to study the produced matter under controlled conditions. Jet quenching phenomena and fluctuation observables let us probe the microscopic interactions and the phase structure of QCD matter.

In order to cover the multi-messenger signals from astrophysical observations, the reaction rates with SM (and beyond) particles need to be taken into account and our studies need to be extended beyond the strong interaction.

This interdisciplinary research project is located at the intersection of astrophysics and heavy-ion collisions and unifies the theoretical efforts, combining thermal field theoretical calculations, numerical simulations and statistical analysis.

Supervisors: Marlene Nahrgang (Associate Professor at IMT Atlantique), Jacopo Ghiglieri (Researcher at CNRS), and Marcus Bluhm (Lecturer at Université de Nantes)
