Kohayakawa (PhD, Cambridge, 1991) is a Full Professor at the Institute of Mathematics and Statistics of the University of São Paulo. He works mainly in the areas of discrete mathematics and theoretical computer science. He was one of the first researchers to promote the use of Szemerédi's regularity method in the sparse setting, focusing on analogues of classical extremal problems in sparse random environments. More recently, he investigated limits of permutation sequences and successfully obtained strong estimates on the number of B_h-sets. His papers on chromatic thresholds of graphs, co-authored with P. Allen, J. Böttcher, S. Griffiths, and R. Morris, received the 2018 Delbert Ray Fulkerson Prize of the American Mathematical Society and Mathematical Optimization Society. He is a member of the Academy of Sciences of the State of São Paulo and of the Brazilian Academy of Sciences.

Ugarte (PhD, 1990, Université Paris-Sud) is professor, Instituto de Física Gleb Wataghin, Campinas, Brazil. His activities have been related to the experimental study of structural and electronic properties of nanoscale systems (nanoparticles, nanotubes, nanowires, etc.), using high spatial resolution techniques associated with electron microscopy. He designed and implemented the Brazilian Electron Microscopy Facility, which was opened in 1999; this microscopy lab was the seed to the subsequent creation of the Brazilian National Nanotechnology Lab in 2011. His prizes include Latsis Prize, École Polytechnique Fédérale de Lausanne, Switzerland; Guggenheim Fellowship, USA; Scopus Prize, Brazil; TWAS Prize in Physics. His is a member of the Brazilian science academy.

Wyse (PhD, 1995, Porto Alegre, Brazil) is full professor of Biochemistry of the Institute of Basic Health Sciences at the Universidade Federal do Rio Grande do Sul, Member of the Brazilian Academy of Sciences. Her prizes include CAPES-Elsevier Award 2014, Pesquisador Gaúcho Award 2018 from the State Research Foundation and Scientist of the Year 2020 Award from International Achievements Research Center, USA. Her research work is focused on the neurotoxic mechanisms of homocysteine and neurometabolic and neurodegenerative diseases, as well as on neurobiology of menopause and neuroprotection, encompassing multiple experimental approach ranging from neurochemistry to behavior. Her studies have contributed to the understanding of biomolecule damage in hyperhomocysteinemic and homocystinuric patients and show potential to improve medical practice. She has published more than 400 scientific papers and has advised more than 70 masters and PhDs. Convinced that access to science and education are pillars to citizenship, she has launched a social project for underprivileged children of the public school system from the outskirts of her town, Porto Alegre. She published a book of poetry.
