I’m a post-doctoral researcher at the Institut Jean Nicod, working with Valerian Chambon and Elisabeth Pacherie. My work explores the relation between the sense of agency, action, and metacognition. In particular, we will investigate how metacognition of action influences the sense of agency and action control, by means of behavioural, computational, and neuroimaging methods.
I completed my PhD at the Institute of Cognitive Neuroscience, University College London, under the supervision of Professor Patrick Haggard. During my PhD, I focussed on how action selection processes inform our experience of agency, independently of monitoring the outcomes of action. A variety of tasks were used to manipulate action selection, both consciously and unconsciously. Additionally, the neural mechanisms underlying the sense of agency were investigated with EEG.
