Workshops & invited talks
I run workshops on applied analytics and, increasingly, on AI in research work — for universities, institutes, and organisations. All materials below are public. Get in touch at luka.sikic@unicath.hr to discuss a workshop for your team.
- 2026SeminarVienna Institute for International Economic Studies (wiiw), Vienna
From frontier ideas to a working 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 the model plans, executes, and verifies before returning for approval. The repository is itself a worked example of the framework.
