Nhat Chung

Nhat is currently a first-year PhD student at  National University of Singapore and is a Graduate Researcher at  A*STAR Singapore , where he is advised by 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.

About

He earned a B.Eng. and a M.Eng. from International University, Vietnam National University HCMC, graduating top of his class. During his studies, he was mentored by Dr. Tuan-Anh Vu in competitive programming and computer vision research. He later worked as an AI Engineer at FPT Software, where he was mentored by Prof. Ngan Le, Prof. Tung Kieu, and Prof. Anh Nguyen in robotics and multimodal systems.

Nhat's technical background spans embodied AI, trustworthy systems, and visual perception.

Embodied AI

Nhat develops semantic representations that help robots connect perception, memory, and action. SlotVLA models objects and their relations for manipulation, while LIBERO-Mem maintains object-centric task states over long horizons, giving embodied agents structured knowledge for deciding what to do next.

Trustworthy Systems

Nhat studies whether semantic representations remain dependable against ambiguities and adversaries. OBEYED-VLA grounds actions in task-relevant objects and geometry, while DepthVanish, MAGIC, and typographic attacks expose how physical and linguistic perturbations can distort understanding and downstream decisions.

Visual Perception

Nhat's visual perception research turns complex scenes into semantic concepts that embodied agents can reason about. Open-vocabulary camouflage segmentation identifies concealed instances, BgSubNet separates foreground dynamics, and UNO represents interactions as scene relations when objects, motion, and context are difficult to interpret.

Nhat's research now asks how semantic representations can support decisions that remain meaningful, grounded, and robust in the open world. The long-term goal is to build contextually safe robots that understand what matters in a scene, recognize when their understanding may be unreliable, and act accordingly around people.
