Luka Šikić
I'm an Assistant Professor of Statistics and Data Science at the Croatian Catholic University in Zagreb. My work sits where quantitative methods meet finance, economics, and digital media. I teach statistics, data science, and digital media, and lead research that connects these fields.
Outside the university, I've worked in financial markets and algorithmic trading, and partnered with firms and research institutes on applied work — financial and time-series econometrics, machine learning, NLP-driven media monitoring, and digital analytics. Most of my current attention goes to AI in economic research: how large language models and agentic pipelines change the way empirical work actually gets done, and which parts of the craft they can't replace. Explore How Economics Absorbed AI, my evidence-based retrospective and forecast, or the open seminar and research pipeline behind this work.

How I got here
PhD in Economics, University of Zagreb and University of Vienna. MSc in International Economics from the Kiel Institute and MSc in Finance from the University of Zagreb. Before joining the Croatian Catholic University, I spent about eight years as a researcher at the Institute of Social Sciences Ivo Pilar and the Faculty of Croatian Studies. My work appears in international and Croatian journals, and I give invited seminars and hands-on workshops on econometrics, data science, and AI-assisted research.
Workshops, consulting, collaborations
I design hands-on workshops in AI for research, applied analytics, and reproducible workflows for universities, institutes, and teams. See previous workshops and public materials, or write to luka.sikic@unicath.hr to discuss a project.
