I am a Research Scientist at Meta Reality Labs. My work focuses on developing advanced on-device solutions to enhance the perception stack for Meta’s MR/VR product lines. I also conduct fundamental research on 3D reconstruction and generative AI.

Prior to joining Meta Reality Labs, I was a technical lead and senior machine learning/computer vision engineer with the Video Engineering Group at Apple Inc. I have lead the algorithm development and delivered the shipments of multiple groundbreaking products, includes Room Tracking on VisionPro, RoomPlan Enhancement and RoomPlan. Additionally, I collaborated with Apple AIML on 3D Scene Style Generation, where we pioneered RoomDreamer, the first paper to enable text-driven 3D indoor scene synthesis with coherent geometry and texture.

I received my Ph.D. and M.S. degree from University of Maryland, College Park, where I was advised by Prof. Rama Chellappa. I completed my B.S. degree in Electrical Engineering and Information Science from University of Science and Technology of China. Additionally, I completed internships at Snap Research and the Palo Alto Research Center.

Highlights

• Feb, 2025, MV-DUSt3R+ is accepted to CVPR 2025. Congratulations to Zhenggang Tang, Yuchen Fan, Dilin Wang, Rakesh Ranjan, Alexander Schwing and Zhicheng Yan

• Jan, 2025, MV-DUSt3R+ is Open Souced. Let’s further push the boundary!

• Dec, 2024. MV-DUSt3R+ is online, a single-stage, multi-view, and multi-path model capable of reconstructing large-scale scenes from sparse, unconstrained views in just 2 seconds!

• Jun, 2024. Room Tracking on VisionPro is unveiled at Apple WWDC 2024. This technology identifies room boundaries, supports precisely-aligned geometries, and recognizes transitions between rooms.

• Oct, 2023. Our paper “RoomDreamer: Text-Driven 3D Indoor Scene Synthesis with Coherent Geometry and Texture” is accepted to ACM Multimedia 2023. [arXiv] [demo]. Congratulations to Liangchen Song, Liangliang Cao and all co-authors.

• Jun, 2023. RoomPlan Enhancement is introduced at Apple WWDC 2023. It added numerous powerful features to RoomPlan, including multi-room scanning, multi-room layout, object attributes, polygon walls, improved furniture representation, room-type identification, and floor-shape recognition.

• Oct, 2022. Our research article, “3D Parametric Room Representation with RoomPlan” is published at Apple Machine Learning Research. Read our research article to learn more!

• Jun, 2022. RoomPlan is first released at Apple WWDC 2022. Combining the power of Apple LiDAR, state-of-the-art 3D machine learning, and an intuitive scanning UI, RoomPlan empowers developers to create innovative solutions in interior design, architecture, real estate, and e-commerce.
