Research Interests

Some of my research interests include the following:

  • Everything related to network management, e.g., performance prediction or anomaly detection
  • Artificial Intelligence (AI) and Machine Learning (ML) in communication networks, including but not limited to
    • Data synthetization via Generative Adversarial Networks (GANs)
    • Usability and Explainability of AI/ML
    • Active Learning mechanisms
    • Uncertainty in AI/ML
  • Network simulation with OMNeT++ and other tools
  • Statistics evaluation and AI/ML in R and Python

Open theses can be found here. Note that a lot of these topics can be tailored to either bachelor theses, master theses or student projects.
