Freire Jr. studied electrical engineering for a year and a half at the Universidade Federal da Bahia (UFBA) before, impressed by the lectures of physicist Benedito Pepe, he switched to physics.[2] He wrote his master's thesis with Amelia Hambuger on interpretations of quantum physics, in particular the interpretation by Vladimir Fock, and subsequently wrote his Ph.D. thesis with Michel Paty and Shozo Montoyama on David Bohm's approach to quantum mechanics.[3]
Freire Jr. is Associate Professor and Researcher II UFBA in the History of Science. He is also president of the Brazilian Society for the History of Science and vice-president of the Commission for the History of Modern Physics, International Union of History and Philosophy of Science.[2]
