**The Luxembourg Institute of Science and Technology (LIST)** is a Research and Technology Organization (RTO) active in the fields of materials, environment and IT. By transforming scientific knowledge into technologies, smart data and tools, LIST empowers citizens in their choices, public authorities in their decisions and businesses in their strategies.

You will join the Functional Polymeric and Particulate Materials (FPPM) RDI unit. The FPPM unit addresses the synthesis, formulation and processing of polymers and (nano)particles to achieve specific properties enhancements and multi-functionality through both experimental and numerical approaches. Materials classes of interest include components (monomers, polymers, additives, (nano)particles, etc.) utilized in high-performance polymeric materials with relevance in the mobility, housing, energy and health sectors. The unit pursues funding and carries out research through industrial contracts and competitive projects sponsored at the Luxembourgish and European levels and is organised into two research groups focused on 1) the realisation of sustainable polymeric and particulate materials (SPPM) and 2) the chemistry and physics of smart / responsive polymeric and particulate materials (RPPM).

The present postdoctoral researcher position is integrated into the RPPM research group and is connected to a recently approved funded project entitled “Evolved materials for multifunctional additive manufacturing printers” (EMMA).
