Research Group Leader
- Development of novel approaches in materials characterization following todays demands, i.e. combination of micro- and nano-structural studies, optoelectronic characterization of micro- and nano-structures, tribology, Laser-Induced Breakdown Spectroscopy (LIBS) and Computed Tomography (μCT, nanoCT).
- Formation of advanced coatings with desirable functional characteristics via the application of advanced technologies and their characterization from macro- down to nano-scale.
Our main objectives are mainly focused on providing insights into current scientific trends and future demands as well as to perform development (R&D) activities within a broad range of topics which include transport (aerospace, automotive), power generation industry, biomaterials and electronics. Worldwide, there is a growing demand for both high-quality multidisciplinary research performance as well as scientific results of excellent quality, reaching the industrial level. In this regard, the research capabilities of the group have been already demonstrated in fundamental research and also through the strong cooperation with a variety of industrial partners in applied research. Thus, we are continuously focused on performing onwards in both national and international multidisciplinary contexts with excellent results.
