Every nation and region is embedded within complex cross-border networks, historical trajectories, and institutional structures. This research portal bridges deep contextual Area Studies with computational Data Science to investigate regional governance, public policy, and socio-economic transformation.

Conducted as part of my full-time doctoral research in Area Studies at Chonnam National University (2026–2030) and based in Osaka City, Japan, my work applies quantitative empirical modeling, causal inference, and computational text analysis to comparative regional studies.

SLIDE 03 · RESEARCH PROBLEMATIC & THEORETICAL FRAMEWORK AREA STUDIES & DATA SCIENCE

Core Problematic: Why Area Studies Needs Computational Data Science Overcoming Methodological Divides in Regional Inquiry

Limitations in Conventional Area Studies Qualitative & Structural Bottlenecks

  • • Small-N Selection Bias: Narrative case studies alone often struggle to generalize across long time horizons and high-dimensional regional variables.
  • • Multilingual Archival Scale: Massive volumes of legislative records, policy white papers, and administrative data across jurisdictions exceed manual coding capacity.
  • • Endogeneity & Spillovers: Regional policy shocks involve complex spatial spillovers and confounding institutional factors.

The Data-Driven Area Studies Paradigm Computational & Empirical Integration

  • • Multilingual NLP & Text Mining: Quantifying policy discourse, regulatory alignment, and institutional sentiment across Japanese, Korean, and English corpora.
  • • Spatial & Panel Causal Inference: Utilizing Difference-in-Differences (DID), Synthetic Control, and spatial econometrics to identify policy impacts.
  • • Contextual Grounding: Pairing reproducible quantitative evidence with deep local institutional knowledge.

Core Research Pillars INSIGHTS FROM AREA STUDIES & DATA SCIENCE

INSTITUTIONS NEXUS DATA MODEL
#01

Comparative Area Studies &
Institutional Transformation Understanding Regional Trajectories Beyond Isolated National Cases

How do cross-border institutional dynamics shape socio-economic outcomes in East Asia?

Anchored in the doctoral program in Area Studies at Chonnam National University (2026–2030) and a research base in Osaka, Japan, this pillar examines how regulatory systems, industrial policies, and demographic shifts co-evolve across East Asian jurisdictions.

By combining comparative political economy with historical institutionalism, we trace both shared regional structures and divergent national policy adaptations.

CAUSAL INFERENCE & NLP
#02

Data Science for
Regional & Social Inquiry Computational Text Analysis, Spatial Econometrics & Causal Inference

Transforming unstructured policy archives and spatial panels into testable evidence.

Applying Natural Language Processing (NLP), large language model embeddings, spatial econometrics, and quasi-experimental designs (DID, Synthetic Control, RDD) to measure policy diffusion, legislative discourse, and regional development performance.

This computational approach brings high-dimensional measurement, transparency, and replicability to traditional Area Studies questions.

GOVERNANCE
#03

Cross-Border Data Governance &
Public Policy Evaluation Digital Regulation, Institutional Trust & Socio-Economic Resilience

Evaluating regulatory alignment and institutional trust in the digital era.

Investigating how jurisdictions across East Asia govern data flows, digital public infrastructure, and regulatory compliance, using empirical policy evaluation to assess the balance between technological innovation and institutional accountability.

Bridging legal-institutional analysis with empirical metrics to inform evidence-based regional governance.
