Research Interests:

As leader of the  Lifespan Neural Dynamics Group (LNDG)  within the Max Planck UCL Center for Computational Psychiatry and Aging Research , I seek to understand how and why the human brain fluctuates so markedly from moment to moment. In particular, we examine brain signal variability and dynamics in relation to six core research foci: lifespan development, cognition, neuromodulation, structural/functional connectivity, transcranial stimulation, and methods/modelling. Accordingly, we have an inherent multivariate focus that allows the examination of brain signal variability phenomena across multiple levels of analysis.
