Embodied AI · 3D Vision · Robot Learning

Chen Liang 梁宸

I am an undergraduate student in the Zhiyuan John Class at Shanghai Jiao Tong University . From February to August 2026, I was a visiting student at UMass Amherst / MIT-IBM Watson AI Lab, working with Prof. Chuang Gan.

My research interests lie at the intersection of embodied intelligence, 3D representation learning, simulation, and world models. I am particularly interested in building scalable learning and evaluation pipelines that connect realistic 3D environments, physical simulation, and general-purpose robot policies.

Biography

I am a computer science undergraduate in the 2023 Zhiyuan John Class at Shanghai Jiao Tong University. In March 2025, I joined Prof. Yunbo Wang's group as a research intern, where I began working on world models, computer vision, and 3D representation learning.

From February to August 2026, I was a visiting student at UMass Amherst / MIT-IBM Watson AI Lab, working with Prof. Chuang Gan. My research there focused on embodied intelligence, 3D representations, simulation, and scalable robot learning.

I am particularly interested in how 3D scene representations and simulation can support scalable embodied learning: from reconstructing and generating interactive environments, to training and evaluating robot policies inside them, and ultimately transferring learned capabilities to the physical world.

More broadly, my interests include world models, vision-language-action models, Real2Sim/Sim2Real, and robot learning.

Miscellaneous

Outside research, I enjoy JRPGs, especially the Xenoblade Chronicles series, and light novels.

I also maintain a personal blog where I occasionally write notes on machine learning, 3D vision, topics I am studying, and JRPGs I enjoy.
