Post-doc. Understand the 3D development strategies of four different brown algae by studying how, when and in which direction cells divide using real-time imaging techniques.


Embryologist at heart and microscopist for fun. The way in which individual cells organise themselves in time and space to form a multicellular organism or tissue is one of my main areas of research, and to do this I use microscopy techniques (light-sheet, two-photon, spinning-disk , etc) in vivo
I first worked on the morphogenesis of the xenopus epidermis as part of my master's degree in Marseille, then on the morphogenesis of the zebrafish olfactory system as part of my thesis in Toulouse. I am now interested in the mysterious model of the brown algae. Not a plant or an animal, the brown algae is a multicellular organism that evolved independently from them. Different strategies of 3D growth exist in brown algae and we are studying four different types found in four different algae using magnificent microscopy.

  • 2018 / 2019 : Master degree in biology integrative and physiology at Aix-Marseille University. Master internship at the Institut of Developmental Biology of Marseille (IBDM) under the supervision of Dr Andrea Pasini to characterize the dynamics of tight and adherent junctions during embryonic epidermal development in the amphibian Xenopus laevis.
