I defended my thesis at the beginning of 2020, on the theme of artificial reefs: "Towards a purposeful construction of a new generation of artificial reefs: Comparative analyzes of the intrinsic factors favoring their colonization from micro to macro-scale" under the co-supervision of Patrice Francour and Cédric Hubas. My research on this topic continues through the HYPER3D project.

HYPER3D is a project led by the ECOSEAS laboratory (University Côte d'Azur) as part of a post-doc co-funded by the Prince Albert II of Monaco Foundation (FP2A) and the Monegasque Association for the Protection of Nature (AMPN). This work is part of a research program on the multi-year monitoring of artificial reefs made with a 3D printer and submerged in 2017 in the Larvotto Marine Protected Area managed by the AMPN.

The research axes of this program are oriented around three questions: (i) do the differences initially observed in the colonization of two substrates used for the construction of artificial reefs (dolomite and concrete) persist over time? (ii) does the colonization of 3D reefs allow the installation of abundant and diverse fauna and flora? (iii) do artificial reefs influence sedimentation and the production of organic matter?

HYPERD 3D will provide response elements by focusing on the analysis of epibenthic communities and of sedimentology through the use of a hyperspectral camera.
