Research Interests
I am currently interested in better understanding the limitations of visual perception by studying different internal factors (e.g., internal noise) responsible for these limitations and measuring how these factors evolve through development from childhood to adulthood. I am interested in neurotypical development as well as neurodivergent development like autism.
I am a postdoctoral fellowship awardee from the Fonds de Recherche du Québec – Santé.
Keywords: visual perception, internal noise, psychophysics, development, autism
