Postdoctoral Researcher in Dynamic Topology

About us

The University of Luxembourg is an international research university with a distinctly multilingual and interdisciplinary character.

The Interdisciplinary Centre for Security, Reliability and Trust (SnT) at the University of Luxembourg is a leading international research and innovation centre in secure, reliable and trustworthy ICT systems and services.
We play an instrumental role in Europe by fueling innovation through research partnerships with industry, boosting R&D investments leading to economic growth, and attracting highly qualified talent. We look for researchers from diverse academic backgrounds to contribute to our projects in areas such as: Network Security, Information Assurance, Model-driven Security, Cloud Computing, Cryptography, Satellite Systems, Vehicular Networks, and ICT Services & Applications.

The SigCom research group of SnT, headed by Prof. Symeon Chatzinotas, focuses on wireless/satellite communications and networking. The research areas focus on the formulation, modeling, design, and analysis of future 6G communication networks that are capable of supporting new services for digital ecosystems. Use cases of interest include Security and Efficient Wireless Communication Solutions, IoT verticals, Unmanned Aerial Vehicles, Integrated Satellite-Space-Terrestrial Networks, Quantum Communications and Key Distribution, Spectrum Management and Coexistence, Tactile Internet, Earth Observation, and Autonomous Transportation. As far as technical enablers are concerned, we leverage expertise on advanced technologies including semantic/task-oriented data processing, signal processing, network resource management to improve the performance of the future wireless communication systems. Finally, due to the large-scale nature, complexity, and heterogeneity of 6G networks, for their analysis and optimization, we use tools such as artificial intelligence/machine learning, graph theory and graph-signal processing, and convex/non-convex optimization. Furthermore, our activities are experimentally driven and supported by the COMMLab, the 6GSPACE Lab, the HybridNetLab, the QCILab, the TelecomAILab, the CSATLab, our SW Simulators, and our Facilities.

Your role

• Develop innovative methods and data-driven AI tools for highly dynamic SatCom systems
• Implement and open-source proof-of-concept software tools
• Collaborate with an international and multi-disciplinary team within the SIGCOM group
• Support ongoing activities related to AI/ML for wireless systems
• Attract new funding related to dynamic wireless communication networks
• Present results at well-known international conferences and workshops
• Participating in outreach events related to AI and SatCom, inspiring young generations to be interested in related topics

The successful candidate will join the SIGCOM Research Group, led by Prof. Symeon Chatzinotas, and contribute to machine learning and AI projects for satellite systems. We are looking for a candidate capable of developing ML models and optimization algorithms specifically designed for highly dynamic satellite communication (SatCom) systems that can handle networks of varying sizes and configurations without requiring retraining from scratch, while maintaining robustness to changes in node order and network topologies. The position offers an exciting opportunity to engage in cutting-edge research that addresses both theoretical challenges and practical applications.
