I did my BSc in Physics at the University of Sao Paulo, Brazil, where I also did my MSc and PhD. After a post-doc at the MIT (Cambridge, MA, USA) from 1987 to 1989 I came to the Universidade Estadual de Campinas (Unicamp) where I am now a full professor at the Physics Department. In the past years I have been working on different aspects of population dynamics. Most of these works were developed using individual based simulations, focusing on processes of speciation and their relation with physical space. In particular, we try to understand the role of partial geographical barriers and natural selection in speciation. We have applied these models to the study of ring species (see Research), where we were able to directly compare the results of the simulations with empirical data.
Parallel to my work in evolutionary biology I also have interest in chaotic and complex dynamical systems, including topics in statistical mechanics and networks. We have recently worked on multidimensional Kuramoto models, extending the coupling constant to a coupling matrix. Such extension breaks the rotational symmetry of the model and generalizes the frustration introduced by Kuramoto and Sakaguchi.
