The selected candidate will investigate the interior structure and evolution of Mercury and will participate in the international project COME-IN (COnstraining MErcury’s INterior structure and evolution) funded by BRAIN-be, the Belgian Research Action through Interdisciplinary Networks. The wealth of data from MESSENGER, the first spacecraft ever in orbit around the planet, is starting to revolutionise Mercury science. COME-IN aims at advancing our understanding of Mercury by integrating complementary approaches from igneous petrology, high-pressure mineral physics, computational materials science, geodesy, and geodynamics.
