With deep sadness, I come to write my first post in Portuguese, an expensive gesture to me.

I have met Artur Ziviani in February/2020 while participating in LNCC Summer Program at their Data Science workshop, organized by him and Professors Fábio Porto (LNCC) and Eduardo Ogasawara (CEFET-RJ). I was attracted by the event’s fame on the quality of presentations, but I wasn’t envisioning that I would earn a friend and an ally on the structuring of a large research project.

We have met twice a week during the last nine months as part of the effort to structure this project, involving several researchers of LNCC and several Brazilian universities on the design of an initiative for uncertainty mitigation of the Brazilian agribusiness supply chains. Unfortunately, the same pandemic which today reaches 300k casualties created a conjuncture that limits project progress, and also today, has taken away this brilliant researcher and dear friend.

I extend my deepest condolences to his family, as well as to friends and fellow researchers. As noted on his bio, Artur’s brilliance and boldness will be missed:

“Artur Ziviani is a Senior Researcher at the Data Extreme Lab (DEXL) of the National Laboratory for Scientific Computing (LNCC), a research unit of the Brazilian Ministry of Science, Technology, and Innovation (MCTI) located in Petrópolis, Brazil. Since 2019, he is the Coordinator of the Multidisciplinary Graduate Program on Computational Modeling at LNCC (M.Sc. and Ph.D.). In 2003, he received a Ph.D. in Computer Science at the LIP6 laboratory of the Université Pierre et Marie Curie (Paris 6) – Sorbonne Universités, Paris, France, where he has also been a lecturer during the 2003-2004 academic year. He received a B.Sc. degree in Electronics Engineering in 1998 and an M.Sc. degree in Electrical Engineering (emphasis in Computer Networking) in 1999, both from the Federal University of Rio de Janeiro (UFRJ), Brazil. From September 2008 to January 2009, he was a visiting researcher at INRIA in France. He is on the Editorial Board of Computer Networks (Elsevier) and IEEE Communications Surveys and Tutorials. His current research interests include network characterization, modeling, and analysis, data science, network science, and interdisciplinary data science research with a networking approach. He is a Member of SBC (the Brazilian Computer Society), an Affiliated Member of the Brazilian Academy of Sciences (2013-2017), and a Senior Member of both IEEE and ACM.”
