Professor Katterbauer’s research interests lie at the dynamic crossroads of artificial intelligence, international law, environmental systems, and digital fiscal policy. He focuses on developing AI-driven frameworks for regulating digital services taxation, including real-time enforcement mechanisms and predictive compliance models for cross-border transactions. In the cybersecurity and IT domain, he explores how machine learning can enhance legal accountability, threat detection, and regulatory adaptation. Additionally, his work in earth sciences integrates 4IR technologies with environmental governance, investigating AI-assisted approaches to resource management, climate risk assessment, and sustainable development. Across all domains, Professor Katterbauer is driven by a central question: how can autonomous systems and intelligent algorithms be harnessed to create law that is both predictive and just, while ensuring environmental stewardship in an increasingly digitized world.
