Tiago Roux Oliveira joined State University of Rio de Janeiro (UERJ), Brazil, as an Associate Professor in 2010. In 2014, he was a Visiting Scholar with the University of California - San Diego (UCSD), CA, USA. He has served as a member of the IFAC Technical Committees: Adaptive and Learning Systems (TC 1.2) and Control Design (TC 2.1), and the Technical Committee on Variable Structure and Sliding Mode Control of the IEEE Control Systems Society (CSS). In 2017, he was nominated as an Affiliate Member of the Brazilian Academy of Sciences (ABC). In 2018, he was elevated to the grade of IEEE Senior Member of the CSS. He was a recipient of the CAPES National Award of Best Thesis in Electrical Engineering, in 2011, and the FAPERJ Young Researcher Award, in 2012, 2015, and 2018. Prof. Oliveira was Guest Editor of the International Journal of Adaptive Control and Signal Processing for the Special Issue From Adaptive Control to Variable Structure Systems - Seeking Harmony. He has served as an Associate Editor for the Journal of the Franklin Institute; the Journal of Control, Automation, and Electrical Systems; the International Journal of Robust and Nonlinear Control; and Systems & Control Letters. In 2020, he was elected Chair of the Technical Committee 1.2 (Adaptive and Learning Systems) of the IFAC for the triennium 2020-2023. In 2021, he was awarded the IEEE Transactions on Control Systems Technology Outstanding Paper Award from the IEEE CSS.

Leonid Fridman has been with the Electrical Engineering Division of the Faculty of Engineering of the National Autonomous University of Mexico (UNAM) in the Department of Control Engineering and Robotics since 2002. His research interests include variable-structure systems. He is a co-author and co-editor of several books and special issues of different journals devoted to sliding-mode control. In 2014-2018 he served as Chair of the IEEE Control Systems Society Technical Committee on Variable Structure
