Graduated in Physics at the University of Brasília (1973), master’s degree in Physics at the University of Brasília (1977),  doctorate in Physical Chemistry at the Université de Paris VI (Pierre et Marie Curie) (1983) and PhD in Physics at the Brazilian Center for Physics Research (1985). Currently is a retired professor at the University of Brasília. Dedicated his research in the field of Theoretical Chemistry in Classical and Quantum Models of Biomacromolecular Systems in the areas of Chemistry, Molecular Biology and Pharmacology. In the past few years has investigated the application of quantum models used in the study of atomic and molecular systems in an attempt to describe the planetary orbits in the solar system and binary star systems. The results of these studies have shown a good correlation between the obtained data by the observation and those derived from theoretical models in a independent mass approach of the celestial bodies. The research has also shown that a single parameter, the mean distance of Mercury’s orbit, can be enough to, through recurrence relations, obtain most of the mean distances observed in the solar system.
