Securing intelligent mobility and making physical AI dependable — from regulation and risk assessment to safe decision-making for robots and vehicles.
Physical AI and intelligent mobility
Robots and vehicles driven by AI now act in the physical world, where a wrong decision
causes physical harm. We study how such systems can perceive across domains, decide
with multimodal models, and know when not to act.
Capability-aware safe meta-decision: the Try-Ask-Refuse framework
Physical AI robots assess their own capability and choose to try, ask a human, or
refuse, so that unsafe or infeasible commands are declined rather than attempted.
See Projects for details.

Cross-domain perception and LLM/VLM-based multimodal decision systems
Perception that stays reliable across countries, roads and sensing conditions, and
decision-making that combines language and vision models for AI-driven mobility,
in joint Korea–Japan research.
Cross-National AI Mobility: from cross-domain perception to LLM/VLM-based decisions
Multi-sensor fusion and adaptive point cloud processing
Fusing camera, LiDAR and other sensors, and downsampling point clouds around 3-D
regions of interest to keep perceptual quality at lower cost.
Automotive cybersecurity
Cybersecurity management systems, UN R.155 and ISO/SAE 21434
Laws and regulations for automobiles now require the reinforcement of security as
well as safety, which reshapes how manufacturers build and certify vehicles.
Automotive regulations for safety and security
TARA and the PIER method for cybersecurity risk assessment
The PIER approach considers cyber-resilience: beyond the risk factors of probability
and impact, it also covers exposure and recovery.
See Projects for details.
