📚 My Research

My research focuses on vision-language-action (VLA) models for robots — enabling aerial and ground robots to understand natural-language instructions and act autonomously in the real world. I am also interested in vision-and-language navigation and learning-based robot control.

Please feel free to reach out if you are interested in collaboration 😃
