Research overview

계산 생체역학 및 환자 맞춤형 모델링

Computational biomechanics & patient-specific modeling

We connect medical images, finite-element analysis, uncertainty assessment, and interpretable prediction to study individualized mechanical risk.

  • Medical-image-based modeling
  • Finite-element analysis
  • Uncertainty quantification
  • Physics-informed prediction

의료기기·로봇·햅틱

Medical devices, robotics & haptics

We develop and evaluate assistive and interventional systems where mechanics, sensing, human interaction, and safety evidence must work together.

  • Continuum robotics
  • Haptic substitution
  • Device mechanics
  • Human-centered systems

디지털 트윈·AI·모델 신뢰성

Digital twins, AI & model credibility

We organize simulation and AI evidence around context of use, model risk, verification, validation, uncertainty, and lifecycle assurance.

  • ASME V&V 40
  • In silico trials
  • Regulatory science
  • AI/ML credibility

Current program

Patient-specific fracture-risk modeling

The group’s active NRF project connects CT-derived geometry, finite-element simulation, physics-informed AI, and risk-informed verification in one traceable workflow.
