PhD Student · A*STAR/NUS · Robot Safety

Nhat Chung

I'm a PhD student at  National University of Singapore and a graduate researcher at  A*STAR Singapore . I work with Prof. Ivor Tsang, Prof. Jin-Song Dong, and Prof. Qing Guo in making robots safer whenever they share space with humans, particularly through learning semantic-action representations and stress-testing.

News

Oct 2026
New preprint Our survey, Towards Human-Centered Safety in Vision-Language-Action Robot Control, is available online! It examines how safety-relevant understanding guides robot actions and reviews methods for design, deployment, and validation.
Feb 2026
Paper accepted LIBERO-Mem @ AAAI 2026 studies whether a robot can remember earlier object interactions across a long manipulation task. It introduces an object-centric benchmark and a slot-based model for tracking that history.
Jan 2026
Paper accepted SlotVLA @ ICRA 2026 studies how compact object and relation representations support robot manipulation. It introduces the object-annotated LIBERO+ benchmark and a slot-based model that uses fewer visual tokens while maintaining competitive generalization.

Paper accepted UNO @ WACV 2026 unifies box- and pixel-level video scene graph generation in one model. Its object and relation slots capture interactions across frames without a separate tracker.

Started my PhD at NUS School of Computing and joined A*STAR's CFAR as a graduate researcher.

Paper accepted BiMa @ ACM Multimedia 2025 tackles bias in text-video retrieval. It uses scene elements and disentangled text features to focus on relevant content, improving retrieval on out-of-distribution videos.

About

I earned my B.Eng. and M.Eng. at International University, Vietnam National University HCMC, where I graduated top of my class. I worked with Dr. Tuan-Anh Vu on competitive programming and computer vision.

Before starting my PhD, I was an AI Resident at FPT Software. There, I worked with Prof. Ngan Le, Prof. Tung Kieu, and Prof. Anh Nguyen on robotics and multimodal systems.

My work has followed three related questions:

Grounded control

I study how robots may learn and use information about objects, their relationships, and their history to guide manipulation. SlotVLA focuses on object relations; LIBERO-Mem looks at what a robot needs to remember across a task.

Stress testing

I test how vision and robot models behave when scenes are cluttered, ambiguous, or deliberately altered. OBEYED-VLA studies object and geometry grounding; DepthVanish, MAGIC, and work on typographic attacks probe failures in perception and reasoning.

I'm now bringing those threads together to study when a robot should trust what it sees and remembers before it acts around people.
