Qihao Liu

Hello! I am a third-year Ph.D. student in Computer Science (CS) at Johns Hopkins University (JHU), advised by Prof. Alan Yuille. I hold a Master of Robotics at JHU. My research interests lie in the fields of 3D computer vision, generative models, robustness, and robotics.

Before that, I received my Bachelors from Shanghai Jiao Tong University. I have also spent great time at Bytedance (with Dr. Song Bai).

Research Interests

My research interests lie in the fields of 3D computer vision, generative models, robustness, and robotics. Specifically, my recent work focuses on:

Image/3D generation and manipulation [ICLR24, CVPR24]
Evaluating and improving ML system with adversarial examination [CVPR23, ICLR24]
Video instance segmentation and tracking [ECCV22, CVPR23]
Human/articulated object pose estimation [Arxiv20, ECCV22]
Reinforcement learning for robot manipulation [IROS21]
