Specializing in Multi-Region Input–Output (MRIO) analysis, Global Value Chains (GVC), International Trade, Structural Decomposition Analysis (SDA), and Emerging & Developing Economies.
I am a quantitative economist specializing in input–output modeling and global value chain (GVC) analysis. My research employs Multi-Regional Input–Output (MRIO) databases and structural decomposition techniques to examine how Asia–Pacific production networks distribute economic gains and environmental burdens across sectors and borders.
My work focuses on the structural position of emerging & developing economies within regional value chains, with particular emphasis on bilateral production and income linkages. This approach provides sector-level evidence on whether economies are moving toward higher-value activities or remaining concentrated in low-productivity, carbon-intensive segments of production.
I completed my Ph.D. in Economics at Yokohama National University. I am particularly interested in empirical research related to GVC measurement, embodied emissions, bilateral income flows, and sectoral development in Asia’s evolving production systems.
MRIO modelling, structural decomposition, and linkage analysis.
GVC participation, value-added trade, and production networks.

Embodied emissions, carbon accounting, and low-carbon pathways.
Role: Author & Maintainer
An official R package available on CRAN for performing Global Value Chain (GVC) analysis. It provides tools to calculate major GVC indicators (participation, position, upstream/downstream length) using standard Input–Output mathematical frameworks.
Role: Developer
A specialized developer package for processing the Asian Development Bank (ADB) MRIO tables. It includes functions for bilateral export decomposition and embodied CO2 accounting not yet available in standard libraries.

Zenodo Data Repository (2025)
A harmonized panel of the Asian Development Bank (ADB) Multi-Regional Input–Output tables. I constructed this dataset to address temporal inconsistencies across vintage releases, creating a stable time-series specifically for long-run structural analysis.

This study traces embodied carbon emissions through Asian production networks to examine how economic growth and environmental pressure are linked across sectors and regions.
In progress. Single-authored.
Using MRIO-based decomposition, this project examines sectoral patterns of bilateral income transfers across Asia–Pacific economies to understand how regional production networks redistribute gains from trade.
