Research Theme

Cognitive and Behavioural Neuroscience


My research interests lie in visual and cognitive neuroscience. In particular, I am interested in understanding the brain mechanisms that support our ability to perceive and categorise objects.

The volume of solid 3D objects is delimited by surfaces, and in my PhD, with Andrew E. Welchman, I used fMRI-guided TMS and psychophysics to study the mid-level neuronal mechanisms that support the perception of 3D surfaces.

Currently, I am a post-doc investigator scientist at the MRC Cognition and Brain Sciences Unit and I explore the neural coding of visual object recognition. I work with Nikolaus Kriegeskorte and Andrew Bell in Oxford where I use functional neuroimaging to investigate the relationship between the categorical organisation observed in ventral visual cortex and the basic visual features being present in individual objects.
