Coupled oscillators / Neuroscience
Oscillations pervade our world. From electronic devices to cardiac pacemaker cells, self-sustained oscillators are found everywhere. Other systems oscillate only under specific perturbations; they are labeled as excitable. For instance, individual neurons may behave either as oscillatory or excitable. Large ensembles self-oscillating and/or excitable units (e.g. neurons) exhibit a plethora of collective behaviors: from global oscillations to complete incoherence.
My research activity focuses on the theoretical understanding of ensembles of oscillators (or model neurons). In my current project I investigate the effect of coupling disorder on the activity of populations of neurons, as well as populations of "rate neurons".
