and control in coupled networks and time-delayed systems“Research Interests
My research focuses on nonlinear dynamical systems, in particular, coupled oscillatorsand excitable systems with applications to neuroscience. I use numerical and analyticalmethods with focus on the study of bifurcations and phase transitions. My goal is to introduce detailed models in neuroscience addressing neurological disorders, e.g. epilepsy.
