Since Feb/2002 I am a Professor at the Nonlinear Phenomena Laboratory (LFNL) - Dept. of General Physics - Institute of Physics - University of São Paulo, where I had my Ph.D. in Experimental Dynamical Systems in March/1999 under supervision of the Prof. José Carlos Sartorelli, I was also a Post-Doc at LFNL from May/2001 to Jan/2002. In December/2005 I presented my Associate Thesis - From Chaos to Biological Neural Networks: The implantation of a new Research Program ath the LFNL-IFUSP. I am also a collaborator at the Institute for Nonlinear Science - University of California, San Diego where I worked with Experimental Neuroscience as a Post-Doc Fellow from May/1999 to April/2001. I had financial support, in both Post-Docs, from the Brazilian agency Fundação de Amparo á Pesquisa do Estado de São Paulo, .
