Wufei Ma

I am a PhD student at Johns Hopkins University, advised by Bloomberg Distinguished Professor Dr. Alan Yuille.

I obtained my B.S. with summa cum laude honor from Rensselaer Polytechnic Institute in 2020 and I had a double major in Computer Science and Mathematics. During my undergraduate years, I had worked with Prof. Bülent Yener on discriminative and generative models for microstructure images and with Prof. Lirong Xia on preference learning from natural language.

I’ve spent great time at Google Research, Reality Labs, Research Asia, CV Science, Research, and collaborated with many exceptional researchers.

SpatialReasoner: Towards Explicit and Generalizable 3D Spatial Reasoning

Wufei Ma, Yu-Cheng Chou, Qihao Liu , Xingrui Wang, Celso M de Melo, Jieneng Chen, Jianwen Xie, and Alan Yuille

arXiv preprint, 2025

3D Vision Vision-Lanugage

Abs Webpage arXiv

We introduce SpatialReasoner, a novel large vision-language model (LVLM) that address 3D spatial reasoning with explicit 3D representations shared between stages – 3D perception, computation, and reasoning. Explicit 3D representations provide a coherent interface that supports advanced 3D spatial reasoning and enable us to study the factual errors made by LVLMs.

Dataset 3D Vision

Abs arXiv Code

We propose 3D-DST that generates synthetic data with 3D groundtruth by incorporating 3D geomeotry control into diffusion models. With our diverse prompt generation, we effectively improve both in-distribution (ID) and out-of-distribution (OOD) performance for various 2D and 3D vision tasks.
