    Interests

    My research focuses on cognitive representations in visual short-term memory, perception, attention, mental imagery and task execution. I am interested in their capacity limits, relationships, and neural substrates. I study healthy adults and aging populations, using a combination of fMRI, MEG/EEG, intracranial recordings, and behavioural tasks, complimented by multiple analysis methods such as multivariate pattern analysis, functional connectivity and causal inference. By studying the links between brain and mind, I aim to understand constraints on cognition, and identify strategies to promote healthy cognitive aging. Collaborative projects also study fluid intelligence in children and glioma patients, and the neural basis of interventions to reduce anxiety.

    Cognitive challenge activates the multiple demand system of the brain (shown in orange, averaged over 252 people). This brain activity weakens with age, which partially mediates decline in fluid intelligence during healthy human aging (green). This relationship is moderated by the variety of physical activities that a person does (bottom right), suggesting that a varied active lifestyle may promote successful cognitive aging.
