Adina Chirila is Assistant Professor at the Department of Mathematics and Computer Science at Transilvania University of Brasov. She obtained her Bachelor’s degree and her Ph.D. in Mathematics from the same university. As an international experience, she spent two years in Germany at the Rheinische Friedrich-Wilhelms University of Bonn, from where she graduated with a Master’s degree. She was also a visiting doctoral researcher at the University of Padua in Italy. Her scientific interests lie in differential equations, partial differential equations, equations of evolution and scientific computing with applications in mechanics.
Marin Marin is Professor in Mathematics at the Department of Mathematics and Computer Science at Transilvania University of Brasov, Romania. In 1994, he received his Ph.D. in Mathematics at the University of Bucharest, Faculty of Mathematics. Also from the University of Bucharest, the Faculty of Mathematics, he received in 2013 the title of “Habilitat Professor”.  In 2012, he received the “Spiru Haret” award of the Romanian Academy, and in 2019 the title of “Professor Honoris Causa” of the Ovidius University of Constanta. Professor Marin is an eminent scientist in Applied Mathematics and has contributed various books as well as research papers in many valuable SCI indexed journals. His WOS H-index is 36.
Andreas Öchsner is Full Professor of Lightweight Design and Structural Simulation at Esslingen University of Applied Sciences, Germany. After completing his Dipl.-Ing. degree in Aeronautical Engineering at the University of Stuttgart (1997), he served as a research and teaching assistant at the University of Erlangen-Nuremberg from 1997 to 2003 while pursuing his Doctor of Engineering Sciences (Dr.-Ing.) degree. From 2003 to 2006, he was Assistant Professor at the Department of Mechanical Engineering and Head of the Cellular Metals Group affiliated with the University of Aveiro, Portugal. He spent seven years (2007–2013) as Full Professor at the Department of Applied Mechanics, Technical University of Malaysia, where he was also Head of the Advanced Materials and Structure Lab. From 2014 to 2017, he was Full Professor at the School of Engineering, Griffith University, Australia, and Leader of the Mechanical Engineering Program (Head of Discipline and Program Director).
