Research interests: I am a PhD student (CIFRE grant by Essilor) co-directed by Angelo Arleo (Vision Institute, Paris) and Catherine Helmer (Lab. of Epidemiology and Biostatistics, Bordeaux). My main research interests are centred on the impact of visual impairment on cognition and functional autonomy in older adults. My project mainly focuses on the epidemiology of ageing, with the aim of understanding how vision losses (due to uncorrected refractive errors, diabetic retinopathy, glaucoma, age-related macular degeneration, and cataracts) influence conditions in ageing, such as dementia, cognitive decline or functional autonomy. For this, we are using a prospective-based study: Three-Cities.

Short bio: I hold a Master degree in epidemiology from the University of Bordeaux (France). During my studies, I was trained in statistics, data analysis of epidemiological studies, public health and epidemiology.

Keywords: epidemiology, longitudinal data, statistics, ageing.
