Beijia Lu

Hi there! I am a Master's student in Computer Vision (MSCV) at CMU Robotics Institute, supervised by Prof. Jun-Yan Zhu.

Prior to this, I graduated from Department of Mathematics, City University of Hong Kong. I am honored to be advised by Prof. Alan Yuille, Prof. Mike Z. Shou, Prof. Ziwei Liu, Prof. Yuan Liu.

Research

My research focuses on generative models, particularly controllable and interactive video generation. I am interested in developing user-friendly and physically grounded generative systems that allow intuitive control and seamless interaction. I am also passionate about understanding the efficiency, structure, and emergent locality of generative modeling to make models more interpretable and scalable.

Miscellaneous

• Sunny is always a clingy little baby, btw can you find Sunny's eyes in the image?
• Huahua and Fugui often fight, but they are also a pair of siblings who can't be without each other.
• They give me the inspiration to strive, and I will love them forever. ❤
