The DFG Research Training Group (RTG) 2723 Materials‐Microbes‐Microenvironments (M‐M‐M): Antimicrobial biomaterials with tailored structures and properties, at Friedrich Schiller University Jena, Germany, combines expertise in materials, life, medical, optical and computational sciences to develop ground-braking and highly innovative antimicrobial biomaterials for the prevention of biomaterials associated infections (BAI). This will be approached by six interdisciplinary PhD tandem projects, each with two doctoral researchers (DRs) working on complementary materials science and medical/life science aspects of these questions in each project, with one materials scientist and one medical/life science professional working as team supervisors.
