Research interests: Older adults exhibit prominent impairments in their capacity to reorient and navigate in unfamiliar environments. In the literature, the impact of visuo-cognitive ageing on spatial navigation abilities remains elusive. I am particularly interested in understanding how modulations of the visual environment affect underlying patterns of brain activity and ultimately spatial navigation across the lifespan. Using structural and functional magnetic resonance imaging (fMRI), I will concentrate on three levels of neural integration: scene-selective regions (at the crossroads between visual and spatial information processing), grid cell-like representations in the entorhinal cortex and hippocampal subfields. This project might provide insights to distinguish the behavioural and cortical changes linked to normal ageing from those related to pathogenic processes characterised by deficits in spatial navigation, such as Alzheimer’s disease.
Short bio: I studied Biomedical Sciences at University College London (UCL). A growing interest for neuroscience led me to conduct my first year Masters project at UCL’s Dementia Research Centre where I examined the impact of GBA mutations on visual cognition in Parkinson’s Disease. For my second-year project I investigated the neural correlates of visuo-spatial information processing in healthy ageing at the Vision Institute in Paris. I obtained my Masters degree in Brain and Mind Sciences from a joint collaboration between UCL, Sorbonne Université and Ecole Normale Supérieure. I am now pursuing a PhD funded by the “Fondation pour la Recherche sur Alzheimer” at the Aging in Vision and Action lab.
