Julian Zobel

Short Bio

Julian studied computer science at TU Darmstadt. From late 2018 to 2022, he was working as a research assistant in the research group "Adaptive Communication Systems" at KOM. Since finishing his PhD thesis focused on autonomous applications of aerial communication networks in disaster situations, Julian pursues his research interests on distributed and infrastructure-independent communication networks, aerial communication support, and aerial network monitoring as a postdoc researcher at KOM.
