I am a neuroscientist interested in understanding the neural mechanisms of perception, decision-making and action, in humans, including, the role of spontaneous fluctuations in brain state and its link to neuromodulation. I use non-invasive neuroimaging techniques and physiological recordings in humans to unveil these interactions and investigate the changes that occur throughout the lifespan with a strong focus on the study of the effect of ageing on brain function and its impact on cognitive decline.
