After completing a classic university course of first cycle, I joined the "Ecole Normale Supérieure-Ulm" of Paris, where I completed a Master degree in Neuroscience co-accredited Paris VI University-UPMC. Since the beginning of my research activity, the field of spinal cord neuronal networks is highly appealing to me as evidenced by my master internship in the laboratory of Dr. Y. De Koninck at Quebec on the study of the synaptic organization of the sensory spinal cord. I continued in the same research field for my Ph.D (MENRT fellowship) in Dr. F. Nagy's lab at Bordeaux where I devoted myself to the study of the plasticity of synaptic connections between dorsal horn neurons, in condition of spinal sensitization to pain. Always in the context of the study of the organization of sensory networks, I chose to realize my postdoc in Dr. F. Charron's lab by selecting a project on the visual system development that fits into an area of research that is both new (developmental biology) and complementary to my previous works on the cellular mechanisms controlling the development of sensory neural networks and the establishment of connections needed to become functional.
