As September 2021, I am working in the MARVEL project, which is receiving funding from the European Union’s Horizon 2020 Research and Innovation program (grant agreement No 957337). The project aims at empowering smart city authorities to better support their citizens. MARVEL deals a set of technologies in the areas of AI, analytics, multimodal perception, software engineering, HPC as part of an Edge-Fog-Cloud Computing Continuum paradigm. These technologies are used to support data-driven real-time application workflows and decision-making in modern cities and showcasing the potential to address societal challenges.
