I'm a first-year PhD student at Nanyang Technological University, supervised by Prof. Ziwei Wang in the PINE Lab. My research focuses on Embodied AI, with interests in Real-World Reinforcement Learning, Bimanual Manipulation, and Imitation Learning. I work on Robot Foundation Models to enable robots to generalize across diverse tasks.
Previously, I received my Bachelor's degree from Wuhan University, where I worked with Prof. Guangyi Yang. I have also worked as a Senior Scientist Intern at A*STAR in Singapore.
A dynamic physical harness that pairs a frozen vision-language-action model with fast execution checks and uses failure evidence to improve its skills through regression-tested revisions.
A robotic foundation model combining vision, language, and force sensing with reinforcement learning for precise contact-rich assembly, trained on the 1,000-hour ManuFacet-1K dataset.
An autonomous intervention system that replaces frequent human corrections in robot RL, using a value-aware critic to detect unproductive rollouts and a memory-guided recovery policy to restore progress.
A test-time trajectory optimization framework for any pre-trained diffusion-based bimanual manipulation
policies, which imposes the safety constraints on bimanual actions.
A plug-in framework that augments vision-language-action models with long-horizon planning via online Monte Carlo Tree Search and kernel density estimation-based confidence sampling.
NORA-1.5 is trained with preference rewards derived from world model predictions and action quality assessments, enabling more robust and generalizable robot manipulation.
A general-purpose zero-shot manipulation framework using an agentic operational graph to decompose and execute complex manipulation tasks without task-specific training data.
REMA improves online robotic reinforcement learning by aligning exploration with a manifold of successful demonstrations, preserving informative near-success trials while penalizing uninformative deviations.
A plug-and-play memory-augmented framework for frozen VLA models that constructs a memory library from demonstrations and retrieves relevant memories via trajectory similarity matching for long-horizon manipulation.
