Ali Ajdari Rad

I am a PhD student in the Laboratory of Nonlinear Systems, School of Communication & Computer Science, at Ecole Polytechnique Fédérale de Lausanne (EPFL). I am interested in Complex Dynamical Networks, influence of the network topology on their dynamics, learning capability of large networks, information propagation and synchronization in complex networks. My advisor is Prof. Martin Hasler.
