Neurodynamics of consciousness Understanding how neural dynamics generate human consciousness is a grand challenge for neuroscience. I develop computational tools that use data from electroencephalography (EEG) to study the network correlates of cognition and consciousness during normal wakefulness, and in altered states like sleep, sedation and meditation.
Predictive coding in cognition The idea that the brain is a hierarchical neural network designed for prediction is persuasive one. In this view, the cortex implements Bayesian inference to maintain a successively complex hierarchy of generative models of sensory causation. I combine EEG and neural network modelling to describe how this predictive mechanism might be implemented in the brain.
Translational neuroscience I apply the science emerging from the study of consciousness to build tools for improving diagnostics and prognostics during emergence from coma, and in prolonged disorders of consciousness (including the so-called vegetative and minimally conscious states). These tools could eventually be deployed right at the patients' bedside to visualise, quantify and track how their brains are recovering after injury. My visualisations of EEG-derived networks of brain activity have been featured by Scientific American’s Science Images and the MRC’s Biomedical Picture of the Day. They have also featured in BBC News, New Scientist, Science Magazine, Wired Magazine, The Washington Post and Der Spiegel, and have sparked a lively debate on Reddit.
