Seminar Dr Pierre Galipot
Read shapes and patterns with PALIMPSEST - Thursday 21 May 2026 11 am, INRAE, Versailles
Objects of interest to humans due to their visual immediacy, forms and patterns participate in numerous biological functions at all scales. Despite the many constraints shaping the potential morphogenetic landscape, an immense diversity of shapes is displayed by living beings. The study of their formation, morphogenesis, is a historical discipline, but the highly integrative nature of its objects means that many gray and unexplored areas remain. Thus, paradigms regularly need to be overcome, and new ways of approaching them seem necessary. To this end, PALIMPSEST project aims to decode forms and patterns to reveal a wealth of crucial information about their morphogenesis and evolution.
Like a palimpsest, a parchment written and rewritten, the central paradigm of this project is to consider that shapes retain visual clues about the events that contribute to their formation, which we propose to interpret using a unique set of image analyses on a large-scale biodiversity database. We hypothesize that this can reveal deep links between two shapes, such as their homology, their nature as different realizations of the same process, the induction of one by the other, or their inter-determination. Using the phylogenetic structure of species into the analysis of shapes, our goal is to further strengthen the force of our conclusions and reveal evolutionary histories of morphogenesis.
