Research Interests

The self, corporeal awareness, disorders of consciousness, art and the brain

In my experience as a clinical neuropsychologist and cognitive neuroscientist, I have been primarily interested in the neurological and cognitive mechanisms of bodily awareness. I have investigated this topic through the assessment of neurological patients, behavioural studies on tactile illusions and neuroimaging experiments. As such, I have developed skills in a number of neuroscientific techniques: experimental design, statistical analysis, lesion analysis, EEG, fMRI, and neuropsychological assessment.

Currently, I am interested in the interactions between language, bodily- and spatial-awareness, and especially what bilingual individuals can teach us about such interactions.
