Research Interests

My research has evolved from efficient visual perception for autonomous systems toward general agents that understand and interact with both digital and physical worlds.

Autonomous Driving

Efficient lane perception, monocular 3D detection, and multi-view BEV representation.

World Models

Learning predictive representations that connect perception, dynamics, and decision-making.

Embodied Intelligence

Generalist agents that reason and act across GUI environments and the 3D physical world.
