Jacob began research in Brazil in quasi-free scattering of protons in light nuclei, a field in which his scientific contribution has gained internatl. recognition. He also did research in Quantum Electrodynamics: the electron muon mass ratio. He held vis. positions at Heidelberg, Maryland, Trieste. In acad. and sci. administration he has taken office successively in the positions of dean of research, dean of planning, vice-rector and rector, all at the Federal U. of Rio Grande do Sul (UFRGS), becoming president of the Brazilian National Council of Scientific and Technological Development (CNPq). Recently, he has done work in science policy, international co-operation, which was started at Münster and resulted in several publications. He has received a number of awards from Brazil, Germany and France. He lately served as an advisory council member for the Brazilian Academy of Sciences.

Artaxo is a professor of environmental Physics at the Institute of Physics, University of São Paulo (USP). He has worked at NASA, Harvard University (USA), Antwerp, Stockholm, Lund Universities, and the Max Planck Institute for Chemistry. His primary interest is in global climate change, focusing on the role of aerosol particles in the radiative balance and on environmental issues in Amazonia. He is a member of the Brazilian Academy of Sciences and the World Academy of Sciences, a fellow of the US AAAS, and a member of the IPCC. He is vice president of the Brazilian Society for the Advancement of Sciences. He has been honored with numerous prizes, such as the Doctor of Philosophy Honoris Causa title in 2009 at the University of Stockholm and the 2024 PIFI Award from the Chinese Academy of Sciences. He is among the most cited Brazilian researchers, with more than 520 papers, 73.378 citations in Google Scholar, and a h-index 127. He has 60.202 citations in the Research ID with an h-index of 122. He published 35 papers in the Science and Nature family of journals. He coordinates the Center for Studies of Amazonian Sustainability from USP.

Cordani is emeritus professor, Institute of Geosciences, University of São Paulo (USP), Brazil. He was trained in geochronology at UC Berkeley (1963) under the guidance of John Reynolds, and obtained his DSc (USP) in 1968. In the 60’s he established a geochronological laboratory that gained international recognition. At the USP he was director of the Institute of Geosciences (1987-1991) and Institute of Advanced Studies (1994-1997). He was president of the International Union of Geological Sciences (1988-1992) and the 31st International Geological Congress (Rio de Janeiro, 2000). He has published ca. 280 scientific articles, and received many awards, among which the Great Cross of Scientific Merit (Brazil), the José Bonifacio Gold Medal (Brazilian Geological Society), and the TWAS medal lecture. He is member of the academies of science of Brazil, Argentina, France and Portugal.

Gambini is professor at the Instituto de Fisica, Facultad de Ciencias, in Montevideo, Uruguay. He is known for his development of non-perturbative techniques for the treatment of gauge theories in terms of Wilson loops, prediction of dispersion effects in the propagation of light due to the quantum structure of space-time, for his consistent discrete quantum gravity approach and for his analisys of the issue of time in quantum gravity. He has recently accomplished the first loop gravity quantization of Black Holes. He is president of the National Academy of Sciences of Uruguay; fellow of the American Physical Society; and member of the Argentinian National Academy of Exact, Physical and Natural Sciences and the Latin American Academy of Sciences. He has won the Gravity Research Foundation Prize three times and the TWAS prize in 2003.
