Dr. Rosa has enjoyed teaching Atoms to Galaxies, Physics 1, Physics for Engineers, Thermal Physics, Statistical Mechanics, Quantum Mechanics, Chaos Theory and Nonlinear Dynamics. His research work is in the field of nonlinear dynamics and computational neuroscience, including synchronization of complex systems. In particular, computational networks of neurons, aligned with collaborative experimental work, is one of his main interests. Networks of neurons play major roles in rhythmic functions in both vertebrates and invertebrates including locomotion, digestion, saccadic eye movement, cardiac and respiratory activities, as well as in pathologies such as epilepsy, Parkinson's disease and depression. Synchronization and rhythmicity are also directly related to memory and information processing in the brain. It is, therefore, difficult to overemphasize the importance of studies in this area.
