Research interests: My current postdoctoral is dedicated to the Silversight project “Healthy Visual Aging, Action and Autonomy” (ANR Research Chair) at the Vision Institute. As a researcher, I am mainly interested in the impact of human aging on vision. More specifically, I investigate the impact of healthy aging on cerebral bases, in relation to visual processing and spatial cognition, using several MRI approaches. Moreover, I am interested by advanced MRI data processing (pre-processing and statistical modelling) as well as optimization methods.

Short bio: I first completed a Master degree in Sport Sciences at the University of Grenoble, France, then a second Master degree in Cognitive Sciences at the Institut National Polytechnique de Grenoble. I pursued as engineer, working on fMRI in monkeys at the Neurosciences Cognitive Center (Lyon, France) during one year. In 2015, I obtained my PhD in Cognitive Sciences from the University of Grenoble Alpes under the supervision of Carole Peyrin (LPNC) and Michel Dojat (GIN). My thesis focused on the study of perception and cognition into the human brain using psychophysics and neuroimaging approaches. More specifically, I investigated (i) the retinotopic organization of spatial frequency processing in visual cortex and (ii) the brain plasticity in normal and pathological (Aged-Macular Degeneration) aging using fMRI associated with retinotopic mapping. In addition, my thesis included methodological developments linked to the acquisition and the processing of fMRI data for applications in a clinical context. In February 2016, I joined the team “Aging in Vision and Action” as a postdoctoral fellow to study the impact of healthy aging on the cerebral bases of vision processing and spatial cognition using fMRI.

Keywords: Spatial frequency, Visual perception, Healthy aging, AMD patients, Spatial cognition, fMRI, Structural MRI, Brain mapping, Retinotopic mapping.
