Title
Project Professor of Energy Market and Data Science
Abstract of Research and Education
My research focuses on the application of time-series analysis to energy trading and energy markets.
I conduct empirical studies on both spot and derivatives markets for electricity, natural gas, and crude oil—examining price formation mechanisms, the transmission of returns and risks, the development of arbitrage and hedging strategies, and the advancement of risk measurement methodologies.
My main research topics include:
- Estimation of elasticities in retail electricity markets
- Evaluation of efficiency in wholesale electricity markets
- Investigation of causal relationships among electricity, fuel, and foreign exchange markets
- Examination of optimal hedging strategies using futures
- Realized volatility analysis using high-frequency data
- Spillover effects of returns and risks across international energy markets and their spectral decomposition
- Arbitrage strategies and market risk management for energy companies
- Impacts of ESG investment on financial markets and corporate value
Through these studies, I aim to provide practical insights for regulators, energy firms, and investors—such as stable and efficient market design, profitability enhancement, risk reduction, and optimal portfolio construction.
By integrating perspectives from both the energy sector and the financial sector, my work contributes to data-driven policy and management decision-making.
Building on this research foundation, I also engage actively in education. At both the undergraduate and graduate levels, I primarily teach courses related to the Kobe Management Data Science Special Study Program (Kobe Management DSP).
