Ongoing Research Projects 

G-LAMP Basic Research Institute Support Program: Quantum-AI Research Institute (Subproject C PI, 2026~2031)

 [G-LAMP 기초연구지원사업: Quantum-AI 융합연구소] (총괄과제 C 책임자, 2026~2031)

I serve as the Principal Investigator of Subproject C (Quantum–AI Convergence) within Sejong University's G-LAMP Program (Global-Learning & Academic research institution for Master's・PhD students, and Postdocs), a major research initiative supported by the Korean Ministry of Education. Beginning in 2026, the program provides approximately KRW 5 billion in annual funding for up to five years to advance fundamental research and foster the next generation of researchers.

My research within G-LAMP focuses on the intersection of quantum science and artificial intelligence, pursuing the complementary directions of “Quantum for AI, AI for Quantum.” Our work explores how AI and machine learning can help model, analyze, and accelerate research on quantum materials, quantum devices, and quantum systems, while also investigating how quantum computation and quantum-inspired approaches can contribute to new AI methodologies.

I welcome inquiries from postdoctoral researchers, Ph.D. students, and prospective graduate students interested in interdisciplinary research at the frontier of Quantum AI, machine learning, uncertainty-aware modeling, and interpretable intelligent systems.

Spectral Multi-Dimensional Emotional Dynamics for Human-Centric Digital Twin Foundations 

[스펙트럴 분석 기반 다차원 감정 동역학 모델링과 인간 중심 디지털 트윈 기반 연구] (PI, Sejong University, 2026~2027)

Foundations of Spectral Multi-Dimensional Emotional Dynamics for Human-Centric Digital Twins 

This project develops a spectral multi-dimensional emotional dynamics framework as a mathematical foundation for future human-centric digital twin systems. Moving beyond traditional low-dimensional representations, emotions are modeled as structured vector–matrix dynamical systems in which emergent emotional outcomes arise from interactions among multiple emotional components and contextual factors. 

By incorporating spectral decomposition techniques such as eigenvalue and singular value analysis, the framework identifies dominant emotional modes that govern stability, amplification, and oscillatory behavior. 

Rather than treating emotions as isolated variables, this approach interprets emotional evolution through latent dynamical structures, enabling a deeper understanding of personalized emotional profiles. The proposed framework establishes a principled and interpretable foundation for predictive emotional modeling, with long-term implications for digital twin technologies, adaptive AI systems, and metaverse-based human interaction environments. 

Soft Computing-based Causal Analysis and Fusion Study on Deep Learning and FNN for TAI(inTerpretable AI) and XAI(eXplainable AI) 

[TAI(inTerpretable AI) 와 XAI(eXplainable AI)를 위한 소프트컴퓨팅 기반 인과관계분석 및 딥러닝(DL)과 퍼지신경망(FNN)의 융합연구] (PI, National Research Foundation, 중견연구과제, 2024~2028) 

Soft Computing–Based Causal Analysis and Fusion for Interpretable and Explainable AI

This research project focuses on developing interpretable and explainable AI frameworks by integrating deep learning with soft computing–based neural models through causal analysis and model fusion.
The goal is to move beyond black-box prediction and enable AI systems whose decision processes can be understood, analyzed, and trusted.

We study how learning dynamics, internal representations, and decision outcomes in deep neural networks can be causally explained and enhanced by combining them with mathematically structured, human-interpretable neural models.
Through this fusion, the project aims to provide theoretical insight, transparency, and robustness in AI systems while maintaining strong predictive performance.

The outcomes of this research contribute to the foundations of inTerpretable AI (TAI) and eXplainable AI (XAI), supporting reliable deployment of intelligent systems in high-stakes, real-world applications.
