I am interested in the cognitive and neural bases of human memory. My research combines behavioural and neuroimaging (fMRI) methods to gain a better understanding of the mechanisms that support retrieval of past experiences and expression of knowledge.

My work is focused on three main research lines:

1. How is our semantic system functionally organized and neurologically implemented. I have investigated how people process concepts, features and categories, their neural representation in healthy adults and the nature of semantic deficits in patients with brain lesion.
2. How we access, select and integrate the meaning of words into context. In a set of fMRI and EEG studies, using semantic ambiguity, semantic illusions and semantic predictability, I explore how the sentential context modulates the attribution of meaning and the underlying neural processes.
3. How people dynamically employ prior semantic knowledge in new episodic learning. I examine the nature of semantic operations that support episodic memory and which encoding and retrieval processes benefit from semantics.
