The primary goal of my ERC StG project ELEMENTS is to provide stringent observational constraints on the cosmic origins of elements heavier
than iron through the analysis - with cutting-edge 3D NLTE models - of high-quality spectroscopic data collected with new astronomical facilities 4MOST. This project thus represents the first large systematic study of s-, p- and r-process nucleosynthesis across the Galaxy.
