My research lies at the intersection of 3D computer vision and graphics, including areas such as visual geometry, 3D reconstruction, point clouds, neural rendering, and more.
My goal is to equip machines with the ability to perceive, simulate, and interact with 3D environments by training deep models.
I am particularly enthusiastic about solving real-world problems using these models.
