Building agents that understand, predict, and act in the physical world.

Head of Embodied Models at EngineAI Robotics

I build closed-loop physical AI systems—from data acquisition and model training to evaluation and real-world deployment.

2026 - Present

Building embodied agents, VLA systems, and world models.

01 · EngineAI Robotics

At EngineAI Robotics, I lead closed-loop data systems spanning acquisition devices, data operations, automated annotation, and data cleaning, together with agent reasoning and task orchestration, VLA policies, and world modeling. This full stack turns robot experience into training data and model capabilities that can understand goals, predict physical outcomes, and act in real environments.

2024 - 2026

VLA / XPlanner for robotic decision and action.

02 · Robot Policy

At XPeng Motors, I led and core-contributed to vehicle-side VLA/XPlanner systems: route-video-to-trajectory modeling, large-model scaling, dynamic interaction, and complex-scenario action generation. I think of this as robot policy learning under real product constraints.

2021 - 2024

Model the world before taking action.

03 · World Models

My prior work at DJI Automotive focused on BEV perception, dynamic object detection, tracking fusion, occupancy-style scene understanding, and 4D annotation loops. These are the ingredients for world-state modeling in deployed robot systems.

2018 - 2021

3D vision as the sensorimotor substrate.

04 · Perception Foundation

I built and maintained practical stereo and depth systems, including X-StereoLab with 600+ stars and 100+ forks. Stereo matching, active stereo, RGB-D understanding, and road-structure perception form the lower-level grounding for robot intelligence.

Mission

Build general, reliable physical AI robot systems.

My goal is to build embodied agents that combine reasoning, VLA policies, and world models, generalize across physical environments, deploy at real-world scale, and continuously improve through closed-loop data.
