Position Details (PhD Research Project)

DistriNet is a world-leading research group at KU Leuven (http://distrinet.cs.kuleuven.be/). Our research focuses on distributed software systems and secure software engineering, covering topics such as the security of IoT systems, cloud applications, enterprise software, and data systems. We aim to develop adaptable, high-quality, and trustworthy software systems.

DistriNet’s applied research unit at Group-T focuses specifically on:
– Intelligent and distributed e-application security
– Security of IoT and cyber-physical systems
The research vision of the group is to design and develop secure software engineering and development tools for ICT systems and applications, with a strong emphasis on IoT. What sets us apart is our commitment to bridging worlds: we combine high-impact strategic research with applied, industry-relevant innovation. This dual approach allows us to make both scientific breakthroughs and create real-world impact.

Project

Communication networks are evolving at a breathtaking pace. The standards that will define tomorrow’s networks are already being designed today. Among the most widely used technologies for connecting devices to the Internet are cellular networks — not just for smartphones and personal devices, but increasingly for security-critical systems. Ensuring their resilience is therefore a top priority. The foundations of security for cellular networks lie in both the security standards defined by 3GPP and their real-world implementations in broadband modem ICs. This project focuses on uncovering security vulnerabilities in these implementations using automated over-the-air fuzzing.
We are seeking a highly motivated and talented PhD who shares our passion for high-impact research. As part of our team, you will:
  • Design and develop advanced fuzzing frameworks for over-the-air fuzzing of cellular network implementations. 
  • Explore the role of AI in boosting the efficiency and coverage of automated fuzzing techniques.
  • Analyse security standards for current and next-generation cellular networks.
  • Contribute to high-impact research at the crossroads of network security, software engineering, and future communications technology.

Profile

We are looking for a candidate who shares our passion for high-impact research and innovation in this critical domain. You are an ideal fit if you have:
  • A Master’s degree in Engineering Technology (ICT, cybersecurity, software development, etc.), Computer Science, or a closely related field.
  • Strong analytical skills and technical expertise.
  • Excellent command of English, both written and spoken.
  • A solid foundation in software security and cybersecurity in general.
Additional assets
  • Practical experience in fuzzing or cybersecurity testing.
  • Familiarity with machine learning concepts or AI platforms.
  • Curiosity, creativity, and the drive to explore new research ideas.

Offer

We offer
  • the possibility to work towards obtaining a PhD degree from KU Leuven – ranked highly in major global rankings – and become a well-trained, independent researcher,
  • a supportive and collaborative team in which you can develop know-how and expertise in state-of-the-art security technologies, 
  • the opportunity to build up research and innovation skills that are essential for a future career in industrial as well as academic research and development environments,
  • support in the further development of your competences towards analysing strategic research problems and to architect and evaluate innovative solutions with industrial applicability,
  • an international and multicultural working environment at the vibrant KU Leuven Group-T Tech Campus,
  • an attractive salary package, complemented with multiple benefits (health insurance, access to university infrastructure and sports facilities, etc.).
