Research

I'm interested in robotics, particularly in robot learning and dexterous manipulation, computer vision, and machine learning. My research focuses on enabling robots to perform dexterous manipulation in dynamic and complex environments, learning to perceive and interact with the world effectively. A key aspect of my work involves learning from human video demonstrations to teach robots nuanced manipulation skills and intuitive interactions, bridging perception and action in real-world scenarios.

ImMimic: Cross-Domain Imitation from Human Videos via Mapping and Interpolation

ImMimic is an embodiment-agnostic co-training framework that bridges the domain gap between large-scale human videos and limited robot demonstrations. It uses Dynamic Time Warping to map human hand poses to robot joints and applies MixUp interpolation to generate intermediate domains for smoother domain adaptation. Evaluations across two parallel-jaw grippers (Robotiq, Fin Ray) and two dexterous hands (Ability, Allegro) demonstrate that ImMimic significantly improves task success and execution smoothness.

We propose SAIL (Speed-Adaptive Imitation Learning), a framework for enabling faster-than- demonstration execution of policies by addressing key technical challenges in robot dynamics and state-action distribution shifts. SAIL achieves up to a 4× speedup over demonstration speed in simulation and up to 3.2× speedup on physical robot.

We develop MimicLabs, a data generation framework to procedurally emulate key sources of diversity in robot datasets. Using this framework, we generate large-scale datasets with controlled variations to analyze how collection diversity and retrieval strategies impact downstream policy learning.
