Dr. Rosa's research work is in the field of nonlinear dynamics with special emphasis on synchronization of complex systems. A particular complex system of interest is networks of neuron. Synchronous networks of neurons are critical in mechanisms associated with rhythmic motions such as mastication, breathing, walking, swimming and flying. Abnormal synchrony has been associated with neurological disorders such as epilepsy, Parkinson's disease, and depression, for example, and in many processes associated with circadian rhythms. In the brain, synchronization is also directly related to memory and information processing. It is therefore difficult to overemphasize the relevance of studies in computational and experimental neuroscience in general, and in those related to synchronization in particular.
