Research

My research lies at the intersection of finance, business analytics, and financial technology (fintech). I develop data-driven and machine learning-based methods to study financial markets, macroeconomic and financial uncertainty, ESG and climate risk, as well as energy and commodity markets. My work integrates high-frequency financial data, textual analysis, and econometric modeling to improve forecasting accuracy and to better understand risk transmission across financial and real sectors.
