About Me

I’m a first-year PhD student at the Language Technologies Institute, Carnegie Mellon University, where I’m fortunate to be advised by Prof. Chenyan Xiong.

Before that, I received my B.Eng. in Computer Science and Technology from Tsinghua University as an outstanding graduate under the guidance of Prof. Yang Liu.

My research explores embodied foundation models to bring AI systems to the physical world with multimodal perception and generation. I’m always happy to chat and collaborate, so feel free to reach out!
