Dr. Kai Wicke joined DLR in 2009 and acts now as head of the department of Product Lifecycle Management at the DLR Institute of Maintenance, Repair, and Overhaul. After graduation, he started working as a research engineer at the DLR research institution of Air Transportation Systems in Hamburg. In 2016, he gained his doctoral degree from the Hamburg University of Technology. His Ph.D. thesis addresses the assessment of aerodynamic technologies on the air transportation system level with respect to economic and ecological impacts. Due to his deeply contextual work contribution and assignment as (sub-)coordinator in internal, national, and European projects he gathered long-term experience within the fields of aircraft lifecycle cost-benefit modelling and assessment, technology assessment, as well as systems analysis.
