My research focuses on cognitive representations in visual short-term memory, perception, attention, imagery and task execution. I am interested in their relationships, capacity limits, and neural substrates. I use a combination of fMRI, MEG/EEG, intracranial recordings, and behavioural tasks in healthy adults and aging populations.  Google Scholar | Cambridge Neuroscience | ResearchGate
