Deokhyun Ahn 안덕현

PhD Candidate, Brain & Cognitive Engineering, Korea University · Student Researcher at KIST AI·Robotics

I am a Ph.D. candidate in Brain & Cognitive Engineering at Korea University and a student researcher at KIST AI·Robotics. My research focuses on video understanding, contextual dynamics, and efficient AI systems for social good.

Starting from sensing-based applications — including a SLAM-based smart helmet for firefighters and indoor drone trajectory tracking — I became interested in reliable real-world systems. I now study how video models can move beyond RGB and motion cues to capture contextual interactions, with recent focus on VLM-guided video anomaly detection for surveillance, especially target-domain transfer and efficient sampling.
