[4][5][6] Brito Cruz began his studies in Electrical Engineering at the Instituto Tecnológico da Aeronáutica (ITA) in 1974 and received his degree in 1978.

[12] Brito Cruz and his team have shown “that 6 femtosecond pulses, which are only three optical cycles long, could be generated by compensating dispersion to third-order.

These short pulses allowed studies to be done in bacteriorhodopsin, organic dyes and semiconductor films.”[13] From 1995 to 1999 he was vice-president of the Brazilian Physical Society (SBF); he has served as editor of the Revista Brasileira de Física Aplicada e Instrumentação.

[8][10] In 2010 Brito Cruz was a member of the 12-member special committee formed by the Inter Academy Council, at the request of the U.N. Secretary General, to review the procedures of IPCC.

Per million inhabitants, Brazil has one-fourth the number of researchers compared to Spain, and one-eighth the number in South Korea.” He suggested that the establishment of new universities financed by federal-state collaboration could result in “institutions that rank among the hundred best in the world in ten years” and could create “opportunities for more young people while developing science and technology in Brazil.”[11] Also in 2012, he gave a plenary session at the Latin America Optics & Photonics Conference (LAOP) in São Sebastião, Brazil.

He was awarded the Grã-Cruz da Ordem Nacional do Mérito Científico (Grand Cross of the National Order of Scientific Merit), presented by the President of the Federative Republic of Brazil, in 2000.

[4] In addition to his scientific papers, Brito Cruz has written a great many articles for the general public, about such subjects as the need for improvements in Brazilian higher education and the importance of research-and-development relations between businesses and universities.
