Data Team Lead @ OeNB

Vienna, Vienna, Austria

About

I lead a supervisory data team at the Austrian National Bank (OeNB), working within the Horizontal Supervision and Strategy Division (HOST). My team focuses on implementing and supporting quantitative, data-driven projects, supervisory technology (SupTech) and artificial intelligence (AI) tools. I have previous experience working as an expert stress test analyst at the OeNB, the European Central Bank (ECB) and the World Bank. The previous work covered topics such as credit risk satellite models, climate risk models, network contagion models and scenario design. I hold a doctoral degree in Economics from the Vienna University of Economics and Business (WU Vienna). My research interests include macro-financial linkages, stress testing, Bayesian time series econometrics, and machine learning models. My dissertation aimed to apply state-of-the-art macroeconomic models to various topics in central banking and financial stability, revealing new insights and fostering a deeper understanding of the underlying mechanisms. Since 2024, I have been passing on my enthusiasm for macroeconomics to Bachelor's degree students at WU Vienna. I am a huge R enthusiast and in love with applying my technical skills to solve more or less complex problems. I also enjoy programming in Matlab, SQL, Python, HTML and CSS, and I have additional experience in C, C++, Java, Stata and VBA.
