Research directions
기계시스템 모델링 및 역학 해석
We study mechanical behavior through mathematical modeling, structural and vibration analysis, finite-element analysis, and comparison with experiments. Applications include medical devices, robotic components, and biological structures.
햅틱·감각대체
We investigate how tactile information can be generated and perceived through haptic devices, including vibrotactile displays and sensory substitution. This work connects device mechanics with human perception and interaction.
모델 검증 및 신뢰성 평가
We study how verification, validation, uncertainty, and evidence requirements support a model’s context of use. Applications include medical-device and robot models, AI models, and in silico clinical trials (ISCT), with credibility assessed for a specific decision.
