Alexandra is a PhD student in the Eccentric Vision lab supervised by John Greenwood. Sam is her second supervisor. Her research compares crowding in our peripheral vision with the elevations in crowding that arise in the central vision of children with amblyopia. She uses both behavioural psychophysics and functional magnetic resonance imaging. She collaborates with our lab on mapping the spatial heterogeneity of crowding and population receptive field measures across the visual field.
