- 2026SeminarComplexity Science Hub, Vienna
Executive overview of the project, presented as a seminar: 710,307 posts across nine platforms filtered on 95 Croatian religious terms, 2021–2026. Five analytical layers — publisher archetypes, sixteen thematic streams, tone and conflict intensity, event-driven spikes, and how influence disperses across the ecosystem over time.

From frontier ideas to a functioning agentic pipeline: a working paper rendered live from Eurostat data and a fully reproducible open-source repository you can clone and run.
- 2026WorkshopCroatian Catholic University, Zagreb
Agentic AI for methodological research: moving from chat prompting to delegating a whole task that the model plans, executes, and verifies before returning for approval. The repository is itself a worked example of the framework.
