Dr. Ruch got his Ph.D. diploma in France in 2002. Since 2005, he had the opportunity to lead groups mainly active on developing innovative  functional materials especially in the field of polymers and polymer-based composites and since 2015, he is leading a research group within Luxembourg Institute of Science and Technology fully dedicated to surface and interface engineering. He published about 200 technical papers and had the opportunity to give more than 40 oral presentations. His fields of interest spans from interface and surface engineering as well as advanced characterization of materials properties up to  (nano)composites processing. He is actively involved in several projects whose aim is to develop multifunctional polymer composites to address specific applications. Throughout his career, he has attracted more than 10 Mio€ of research funding. Ongoing research projects are focused on developing Nanostructured coatings for one one hand to improve interfacial adhesion between symmetric or disymmetric materials and on the other hand to develop innovative multi-functional thin films.
