RESEARCH 

 

I am interested in problems which are substantial in nature and related to geometry, dynamical systems and their interactions. They are usually situated on the frontiers of traditional areas and call for the application of a diverse range of techniques. Recently, in collaboration with other researchers, we have initiated the study of the evolutionary dynamics of complex networks and its applications in the areas of systems biology and innovation processes in economy.

 

I am responsible for the GeoDynApp team (Spanish Excellence Grant MTM2016-77642-C2-2-P) which is part of the ECSING research group and the USC group of Foliations and Dynamical Systems.

 

I currently work in collaboration with Françoise Dal'Bo (Rennes), Gilbert Hector (Lyon), Matilde Martínez (Montevideo), Ana Rechtman (Strasbourg), Paul Schweitzer S.J. (Rio de Janeiro) e Alberto Verjovsky (Cuernava).
