Research interests:  It is well known that aging alters vision. But beyond presbyopia, the factors responsible for the loss of sensitivity of various visual functions remain poorly characterized. Light is one of them and it plays a role even in some non-visual physiological pathways. In the framework of the Silversight II Chair “Healthy & Pathological Visual Aging, Spatial Cognition, Autonomy”, I will investigate how these light-sensitive brain pathways evolve with age. Furthermore, I will explore how light affects visuo-spatial processing, cognitive and memory functions and to what extent some combination of lights can improve them.

Short bio:  After a Physics-Photonics engineering degree at Institut d’Optique Graduate School in Paris-Saclay, I pursued my studies at KTH, Royal Institute of Technology, in Stockholm and completed a biomedical master. There, I developed knowledge and skills in physics towards applications and research in life science. My will to work in an interdisciplinary environment led me to conduct my MSc thesis in the context of a collaboration between ALPHANOV, an optics and laser technology center, and INSERM BioTis on a tissue-engineering project for regenerative medicine. In June 2018, I joined the CHANEL company to better understand interactions of light and skin, develop diagnostic tools, and organize clinical studies. In January 2020, I joined the Vision Institute, and in particular the Aging in Vision and Action lab, as a research engineer.

Keywords: Healthy & pathological visual aging, fMRI, EEG, eye movement, light sensitivity & adaptation, memory, spatial cognition, decision-making.
