Research
I'm interested in robotics, human-robot interaction, computer vision, and reinforcement learning.
Much of my research is about applying mathematical concepts/theories to robot learning. Representative papers are highlighted.
Evaluating robot motions involves more than just the start and end states; it's about how the task is performed. We propose motion instruction fine-tuning (MotIF) and MotIF-1K dataset to improve VLMs' ability to understand nuanced robotic motions.
We propose a novel framework that facilitates efficient personalization of robotic agents to diverse human preferences in complex environments.
