Current Research Interests

  • Visual perception
  • Computational modelling of visual processing
  • Visual imagery and memory
  • Cortical reorganisation following damage or disease

Research Interests

Research in my lab seeks to understand the neural mechanisms underpinning visual perception and memory in the human brian. In particular, my work focuses on understanding how cortical regions develop functional specialisations (e.g. for faces or words) and how such specialisations interact with other cortical systems, such as memory. My lab uses a diverse set of neuroimaging and neurostimulaton techniques including fMRI, EEG and TMS. These are combined with eye-tracking and behavioural psychophysics to bring converging evidence to bear on these questions. 

Current research projects are investigating:

  • The influence of visual field biases on categorical representations
  • The impact of retinal gene therapy on patients with retinal disease
  • The neural mechanisms linking vision with memory

My research in a nutshell

I study visual perception and memory using behavioural, computational and neuroscience techniques. The primary areas of my research are (1) understanding the ways that different regions of visual cortex operate and interact in order for us to make sense of complex visual environments, (2) understand how vision and memory interact with each other and (3) assessing the impact of brain damage/disease on the function of the visual cortex. My research in these areas aims to understand and answer fundamental questions about how the visual brain works in order to better aid those with visual deficits.
