I am studying how previously learnt knowledge and predictions lead to efficient representations in the brain and how such predictions facilitate face perception.

In my work with macaque monkeys, I focus on sensory predictions about visual features of faces based on information learnt on timescales of a few hours using functional magnetic resonance imaging (fMRI) and in-vivo electrophysiology. I complement this by studying how abstract and conceptual predictions learnt through contextual cues and regularities acquired through a very few repetitions affect perception in humans using invasive electrophysiology (iEEG).
