Research

My main interest is human visual cognition – that is, I want to know how the brain provesses visual objects and scenes.

I have the pleasure to collaborate with a great set of scientist towards this goal in my lab.

In particular, the lab wants to find out (1) how the brain transforms sensory into abstract representations, (2) how exactly feed-forward and feedback information mediate vision, and (3) how plastic the underlying neural architecture is by studying visual cortex in the blind.

We use a combination of methods (fMRI, M/EEG, deep neural networks, behavioral assessment), and analyse data in an integrated framework using machine learning techniques and representational similarity analysis.
