**About the Editor**

**Robert Pederson** (Professor) is Professor of Engineering Materials and Head of Division of Subtractive and Additive Manufacturing at University West, Sweden. Robert has 20 years of experience within the research and development of advanced metallic materials for aerospace and space applications. He received his PhD in 2004 working on a project on titanium alloys in close collaboration with Volvo Aero Corporation (which became GKN Aerospace Engines Systems Sweden in 2012). During 2004–2016, Robert worked at Volvo/GKN as a research cluster leader, company specialist in materials technology, project leader, project manager, and responsible materials application engineer in a number of projects related to civilian aero engines as well as space rocket applications. In 2013, he became Associate Professor at Chalmers University of Technology; in 2015, he was appointed Adjunct Professor at Lulea University of Technology; and he has served as Full ˚ Professor at University West since 2016. He has supervised 5 PhD students in the completion of their doctoral degree and is currently supervising 3 PhD students. The research work conducted in his laboratory is focused on exploring and improving understanding of the thermomechanical processing–microstructure–mechanical properties relationship for titanium alloys and other metallic alloys, and the key technologies of welding and additive manufacturing processes used by the aerospace and space industry.
