  Research Overview

  
  Our laboratory is dedicated to the design and discovery of innovative materials and devices that will support future society by integrating mechanics of materials, computational physics, data science, and artificial intelligence (AI).
  We address some of the most pressing scientific and technological challenges facing humanity, including space exploration, carbon neutrality, next-generation AI, and quantum computing. By leveraging state-of-the-art supercomputing and AI technologies, we investigate phenomena spanning from the atomic scale to the macroscopic scale and develop novel materials with unprecedented functionalities.
  
  

  Research Topics

  
  🚀 Innovative Materials for Exploring the Frontiers of Space
  We study self-healing materials and ultra-high-strength materials capable of withstanding extreme conditions such as severe mechanical stresses and external fields.
  Our goal is to develop next-generation materials that will enable future space exploration missions and advanced aerospace systems.
  
  🌱 Energy Materials for a Carbon-Neutral Society
  We develop energy-harvesting materials that convert unused ambient energy—such as vibration, heat, and light—into electrical power.
  Through these efforts, we aim to contribute to sustainable energy technologies and a carbon-neutral future.
  
  ⚛️ Quantum Materials Science for the Age of AI and Quantum Computing
  We explore novel functional materials and quantum devices that exploit quantum phenomena emerging in the world of atoms and electrons on the nanometer scale.
  Our research seeks to establish breakthrough technologies for next-generation AI systems, quantum computing, and beyond.
  
  🧩 Materials that Compute: Toward Intelligent Matter
  To realize future intelligent systems in which materials themselves can process and learn information, we investigate neuromorphic and intelligent materials based on skyrmions, where geometry and material functionality are intimately coupled.
  This research opens new interdisciplinary frontiers bridging mechanics, geometry, condensed matter physics, and information science.
  
  🤖 Data-Driven Materials Discovery with Supercomputing and AI
  We utilize supercomputers, machine learning, and proprietary theoretical-physics-based datasets developed in our laboratory to dramatically accelerate materials discovery, which has traditionally relied heavily on trial-and-error and empirical intuition.
  Our vision is to establish next-generation materials design methodologies by integrating theory, computation, and artificial intelligence.
