Biography

I joined Apple after graduation. Previously, I received my Ph.D. degree in Computer Science at UC Berkeley. My dissertation is on “Learning to Detect Geometric Structures from Images for 3D Parsing”.

I am interested in 3D vision, computer graphics, and artificial intelligence. My recent research focuses on integrating geometric concepts and data-driven approaches into a unified framework. To this end, I design methods to extract high-level geometric structures from images, such as lines, wireframes, vanishing points, and symmetries, and use them to parse scenes into high-quality compact CAD-like 3D models and achieve robust localization.
