#### **Nenad Gubeljak**

Full Professor Nenad Gubeljak studied Mechanical Engineering at the University of Maribor in Slovenia, where he completed his M.Sc. in 1991 and Ph.D. in 1998. During his postgraduate study, he was awarded an Arge Alpe-Adria scholarship in Austria, a Slovenian national foundation grant, and a DAAD scholarship in Germany. For his contribution to the behaviour of mismatch welded joints, he received the Henry Granjon prize from the International Institute of Welding (IIW) in the "Integrity of welded constructions"category in 1999. For the project "Mis-matching effect of constraint", he earned a Marie Skłodowska Curie post-doctoral scholarship from the European Commission, and was a guest scientist at the GKSS research centre Geesthacht in Germany in 2000–2001. As a member of a consortium from Slovenia in the period from 2003 to 2012, he led EU projects in the framework FP6, FP7 (Fitnet, Hiperc), as well as CemLib in Eureka projects MOSTIS and OLMOST. In 2011, he was named Guest Professor at the Institute of Mechanics, Universite de Lille, France. In the last 10 years, he has led bilateral projects with foreign science institutions and universities in Argentina, Belgium, the United States, France, Austria, Czechia, Russia, Croatia, and Serbia. As a member of a consortium from Slovenia, he leads the KOMET 2 project of the Austrian Academy of Sciences. He is a member and a representative for Slovenia in the European Association for the Integrity of Constructions ESIS. He is a member of the American Association for Standardisation of Material Testing, ASTM section E0.8 for fractures and fatigue. At the Faculty for Mechanical Engineering in Maribor, he is head of the Chair for Mechanics. Mostly in cooperation with foreign scientists, he has published more than 180 scientific research articles in international journals, as well as contributions in international conferences. These papers are related to fatigue and the fracture behaviour of structural materials and welded joints.
