About the role...
This is a fully funded postdoc position for 2 years within an EU project (XTRUST-6G: Extended zero-trust and intelligent security for resilient and quantum-safe 6G networks and services). The position offers a unique opportunity to advance cutting-edge research at the intersection of AI/ML, physical layer security, and next-generation wireless networks.
The main objectives of this position align with the directions of XTRUST-6G:Enhance the physical layer security of satellite and wireless communication systems using AI/ML techniques.
- Enhance the security of UAV-enabled wireless communication systems at the physical layer using AI/ML techniques.
- Develop and apply adversarial training methods to strengthen machine learning models against intentional interference related to adversarial attacks.
- Design, optimize, and implement anti-jamming in UAV communication systems.
The successful candidate will work under the academic supervision of Dr. Jorge Querol (University of Luxembourg) and join a strong and motivated research team led by Prof. Symeon Chatzinotas.
The successful candidates are expected to perform the following tasks:
- Develop machine learning-based solutions to secure UAV-enabled communication networks at the physical layer, addressing challenges such as high mobility, dynamic topologies, and intermittent connectivity
- Investigate and implement adversarial training frameworks to protect machine learning models from intentional threats, including jamming targeting UAV communication channels
- Develop and implement a software and hardware testing environment for UAV. communication systems, enabling real-time validation of proposed techniques
- Utilize platforms like USRP/SDR-based testbeds to demonstrate system feasibility and performance
- Disseminating results through scientific publications and conferences
- Contribute to the different research projects, either coordinating technical contributions and/or preparing project deliverables
- Preparing new research proposals to attract industrial, national, and European projects
- Eventually provide assistance in the supervision of PhD students
For further information, please contact: Dr. Jorge Querol () / Dr. Marcele Kuhfuss ()
