During and after my PhD thesis (1989), I worked on traditional Statistical Mechanics problems, mainly related to magnetic phase transitions. In 1984, during a visit of Professor D. Stauffer to our Institute, I was introduced into the subject of Biological Ageing, and since then I have been working on modeling interdisciplinary evolutionary systems. Using and adapting the computational Penna model described in the second chapter of this book I have studied and simulated the Catastrophic Senescence of Pacific Salmon, the advantages of sexual reproduction in comparison to the asexual one, why does menopause evolve, why are we diploids instead of triploids, etc. Presently I am mostly interested in speciation processes where no physical barrier prevents the gene flux between different subspecies. I was elected the Vice-Director of my Institute from 1995 to 1999 and the Vice-Coordinator of the PhD Course from 2001 to 2003. Since 2003 I am the Secretary for Development of the University.
