Lingjie Liu

Lingjie Liu is the Aravind K. Joshi Assistant Professor in the Department of Computer and Information Science at the University of Pennsylvania, where she leads the Penn Computer Graphics Lab and is a faculty member of the GRASP Lab. Her research sits at the intersection of computer graphics, computer vision, and artificial intelligence, with a particular focus on neural scene representations, neural rendering, human performance modeling and capture, and high-quality 3D reconstruction. Liu’s work explores new classes of algorithms that merge classical graphics pipelines with deep learning approaches to produce realistic, controllable, and efficient 3D and 4D representations of people and complex environments. Before joining Penn, she was a Lise Meitner Postdoctoral Research Fellow at the Max Planck Institute for Informatics and received her Ph.D. from the University of Hong Kong. Her long-term research vision aims to develop AI technologies capable of perceiving, understanding, and interacting with 3D worlds. This includes advancing sparse-input 3D reconstruction, photorealistic scene synthesis with explicit 3D control, and large-scale 3D scene generation, with applications in immersive media, simulation, robotics, and next-generation virtual environments.
