The Complex Systems Group has extensive experience in the study of complex systems, processing of massive data, nonlinear dynamics and chaos , and is strongly interdisciplinary in nature, researching in areas as varied as physics, mathematics, optics, sociology, medicine, biology and agri-environment. He is also very active in the direction of Doctoral Theses within the Doctoral Program in Complex Systems of the UPM .It is part of different thematic networks, such as COMSOTEC (Complex Socio-technological Systems), DANCE (Dynamics, Non-Attractors). Chaotic and Stability), ISMC (International Soil Modeling Consortium), GUMNET (Guadarrama Monitoring NETworking) and AGRISOST (SUSTAINABLE AGRICULTURAL Systems). This makes GSC actively participate in the meetings of the different Networks and maintain collaborations with various centers in the USA (Center for Nonlinear Sciences, Georgia Institute of Technology, MIT, New England Complex Networks Institute, University of California, University of Texas , John Hopkins University) and Europe (Rothamsted Research, University of Reading, UfZ Leipzig, Potsdam Institute).
