Marcel Altendeitering

Dr.-Ing. Marcel Altendeitering heads the Mobility & Smart Cities department at the Fraunhofer Institute for Software and Systems Engineering ISST in Dortmund. His research focusses on trustworthy AI, which he pursues along two complementary paths: first, through approaches involving data sharing, such as federated data ecosystems, data spaces or data trustee models, in which data is shared across organizational boundaries in a sovereign manner and which support the context engineering of agents and LLMs with high-quality data. Second, through approaches without data sharing, such as (decentralized) federated learning, where AI models are trained in a decentralized way without exposing sensitive data. Both directions are connected by data quality management as the foundation of reliable AI results – a topic to which he already dedicated his doctoral research at TU Dortmund University.
