David Gerhardinger, Ph.D., is a Senior Assistant at the Department of Aeronautics, Faculty of Transport and Traffic Sciences, University of Zagreb, and Head of its Laboratory for Testing in Aeronautical Engineering. He holds B.Sc. and M.Sc. degrees in aeronautical engineering and earned his Ph.D. in 2023 with research on remaining useful life prediction for light-aircraft structures using limited operational data. His research focuses on structural fatigue, aircraft ageing, prognostics and health management, and physics-based and data-driven approaches to aircraft maintenance. He has published related studies in Aerospace (2023), Applied Sciences (2025), and Transportation Research Procedia (2022). Previously, he worked in aircraft production management and R&D, overseeing production of 51 light aircraft and assembly of 16 helicopter composite airframes. He is authorised by the Croatian Civil Aviation Agency to supervise and approve work on nationally regulated aircraft and performs aviation-related court expert assessments. His teaching covers aircraft structures, systems, propulsion, and maintenance.
