Tenenblat obtained her MSc (1969) at the Univ. of Michigan and PhD (1972) at the Instituto de Matemática Pura e Aplicada, Rio de Janeiro. She has served in various capacities at the Univ. de Brasilia, Brazilian Mathematical Society, Ministry of Education, Ministry of Science and Technology (Brazil) and other organizations and committees. She is professor emeritus of mathematics at the Univ. de Brasilia. An expert in differential geometry, she has advanced understanding of the interaction between differential geometry and partial differential equations. With S.S. Chern and other collaborators, she helped develop the classification of systems of differential equations that describe pseudo-spherical surfaces. Her membership includes: Brazilian Mathematical Society; American Mathematical Society; Brazilian Academy of Science; and Brazilian Society for the Advancement of Science. She received the Comendador de Ordem Nacional do Merito Cientifico from the President of Brazil in 1996.

Colli, a biochemistry professor at the U. of São Paulo (USP), received his PhD under the supervision of Isaias Raw and did postdoc work at PHRI, NYC, USA with M. E. Pullman (1966-1968) and M. Oishi (1968-1969). Returning to Brazil in 1970, he established a group, at the Ins. of Chem. (IQUSP), to work with Molecular Parasitology, particularly with Trypanosoma cruzi, the agent of Chagas' disease. He was dean of IQUSP twice, and of the Butantan Inst. (the Snake Farm). He was pres. (2006-2009) of the Brazilian Technical Committee on Biosafety (CTNBio). He received the title of Doctor (h.c.) from the U. of Buenos Aires, the Great Cross Medal of the Natl. Order of Scientific Merit from the Brazilian govt. and is a member of the Brazilian Acad. of Sciences. In 2014 he was awarded the Almirante Álvaro Alberto Prize for Science and Techn., the most prestigious scientific prize in Brazil. Since 2003 he is an Associate to the Science Director of FAPESP for the areas of Health and Biology.

Simis is emeritus full prof., Federal U. of Pernambuco, Brazil, and presently a FAPESP Vis. Sen. Researcher at ICMC-USP. He is First Class research grant recipient from the Brazilian Research Council. He earned his PhD from Queen's U., Canada. In Brazil, he was prof. at IMPA in Rio de Janeiro until 1980. He was president of the Brazilian Mathematical Society and has been member on several occasions of international commissions of the IMU and TWAS. He has been director of 3 workshops in his field at the ICTP. He is a recipient of the Natl. Medal Grã-Cruz for Scientific Merit, Min. of Science and Technology, and was a JS Guggenheim Fellow. He has been awarded other fellowships from the Max-Planck-Institut, Japan Soc. for Promotion of Science and the Istituto Nazionale di Alta Matematica. He is a member of the Brazilian Acad. of Sciences and serves on several committees in Brazil. His mathematical work concerns the interlaciing of commutative algebra and algebraic geometry.

Linden is Full Professor, Head of the Laboratory of Neurogenesis, and former Director (2004-2007) of the Institute of Biophysics Carlos Chagas Filho, at the Federal University of Rio de Janeiro. His research work is directed at mechanisms of development of the central nervous system and neurodegeneration. His achievements in cellular neurobiology have led him to become a senior investigator of the Brazilian National Research Council and a John Simon Guggenheim Fellow in 2002. He received the Grand-Cross of the Brazilian National Order of Scientific Merit in 2007. He is also a senior member of the Brazilian Academy of Sciences (1998) and member of the Latin American Academy of Sciences (1999).

Barbosa is professor in the Departamento de Matematica, Universidade Federal do Ceara, Campus do PICI, Fortaleza, Brazil. A well known mathematician and expert in differential geometry, he has made outstanding contributions to the stability of minimal immersions of surfaces in the Euclidean space, and towards precise, simple conditions to decide when critical points for the variational problem of minimizing area are minimal. He has been awarded the Medal of Scientific Merit of Brazil, is fellow of the Brazilian Academy of Sciences and of the Academy Cearense of Sciences, and is a member of the Brazilian and American Mathematical Societies and the Brazilian Society for the Progress of Science. He was, for two terms, the president of the Brazilian Mathematical Society. Recently he became Professor Emeritus and President of the Ethics Commission of the Universidade Federal do Ceará.

Sial is full professor (retired, 2012; Emeritus Professor, 2016) in the Department of Geology, Federal U. of Pernambuco, Brazil (UFPE). He obtained his PhD from UC Davis (1974) and did postdoctoral work at the U. of Texas at Austin (1977-78), U. of Georgia at Athens (entire 1983, entire 1988) and U. of Wisconsin (2001). He also trained in Portugal, Canada, Japan and Scotland. He founded a Laboratory for Stable Isotope Studies at UFPE, only one in South America with facilities to analyze O isotopes from silicates, and pioneered the use of isotope stratigraphy in S. America. He has received several honours including: Silver Hammer and José Bonifacio Golden Medals (Brazilian Geological Society); Centennial Medal, Engineering School, UFPE; National Order of Scientific Merit commendator and Grao Cruz classes (by President of Brazil decree); special foreign member, Society of Resource Geology, Japan; and foreign member, Brazilian Academy of Sciences, Lisbon Academy of Sciences, Portugal.

Campos de Carvalho was Director of the Department of Science and Technology at the Ministry of Health in Brazil.
