Research Theme

Cognitive and Behavioural Neuroscience

Interests

The research that I have been undertaking investigates how information about meaningful objects is represented in the brain. More specifically, this is centered around how information about objects develops over time, and how the responses of different brain regions reflect different conceptual knowledge across time. In addition, I'm also interested in the mechanisms by which these different brain regions interact culminating in meaningful object representations.
