Scientific summary

My main interest is to understand how proper neural connections are established during brain development. I use mouse visual system as a model to analyze the contribution of activity dependent and independent mechanisms in the formation of connectivity. Retinal projections form a visual map in their target organized in a topographic and eye-specific manner. This specific organization is crucial for vision and allows to easily map any defects caused by improper targeting. My aim is to understand how activity and molecules shape the visual map during brain development. In addition, we try to understand how pigmentation affects vision, as people with albinism have all visual problems linked to abnormal development of the eye. We combine mouse genetic methods, in utero and ex vivo retinal electroporation techniques together with cell culture, tracing and histological methods.


I am part of the team of Dr. Patricia Gaspar at the Institut du Fer à Moulin (IFM). The Institut du Fer à Moulin (IFM) is an INSERM research center devoted to the study of the development and plasticity of the nervous system.
