Feiran Wang

Hi, I'm Feiran, a third-year PhD student at the University of Illinois Chicago under the supervision of Professor Yan Yan. This summer, I was a research intern at the Bosch Center for Artificial Intelligence (BCAI), mentored by Dr. Xiaoqi Wang.

My research centers on Spatial Intelligence, with the interest of empowering intelligent agents with the spatial understanding, physical reasoning, and interactive capabilities needed to operate effectively in the real world. My research spans 3D foundation model, world model, medical imaging, self-evolving agents and Physical AI.

I hold an M.S. from the University of Illinois Urbana-Champaign, where I was advised by Professor David Forsyth, and a B.S. from Shanghai University advised by Professor Xiaoqiang Li. Before joining UIC, I spent two years at the Illinois Institute of Technology. I also made academic visits to the University of Michigan and the University of Toronto.

Work Experience

Bosch · Research Internship
2026 May to August · United States

Long-tail dataset generation for autonomous driving. Focusing on 3D-based data synthesis and scene editing to improve perception model robustness in rare and safety-critical scenarios.

Publication

RayMap3R
RayMap3R: Inference-Time RayMap for Dynamic 3D Reconstruction
ECCV, 2026

We revisit and observe that RayMap-based predictions exhibit inherent static scene bias and propose RayMap3R, a training-free streaming framework for dynamic scene reconstruction.

LIST3R
LIST3R: Long-sequence Instance-aware 3D Reconstruction
Jing Gao, Wei Wang, Feiran Wang, Yan Yan
Preprint

We present LIST3R, an instance-aware framework for long-sequence 3D reconstruction inspired by the way humans organize spatial memory around stable and recognizable objects.

CIF
Consistent Instance Field for Dynamic Scene Understanding
CVPR, 2026

CIF formulates a continuous probabilistic field over object existence and identity in space-time, enabling consistent instance representations across views for dynamic scene understanding.

GPF
From Particles to Fields: Reframing Photon Mapping with Continuous Gaussian Photon Fields
Preprint

GPF reformulates photon mapping as a continuous radiance field of 3D Gaussian primitives, achieving photon-level accuracy for global illumination with greatly reduced computation.

CogniMap3D
CogniMap3D: Cognitive 3D Mapping and Rapid Retrieval
ICLR, 2026

We present CogniMap3D, a bioinspired framework that maintains a persistent memory bank of static scenes, enabling efficient spatial knowledge storage and rapid retrieval.

X-Field
X-Field: A Physically Informed Representation for 3D X-ray Reconstruction
NeurIPS, 2025 (Spotlight)

Rooted in the X-ray imaging process, X-Field presents a representation specifically for high-quality X-ray Novel View Synthesis and CT Reconstruction.

ZECO
ZECO: ZeroFusion Guided 3D MRI Conditional Generation
MVA, 2025 (Oral)

To mitigate medical data scarcity, ZECO synthesizes high-quality 3D MRI images across various modalities, conditioned on segmentation masks.

PCCN-RE
PCCN-RE: Point Cloud Colourisation Network Based on Relevance Embedding
Feiran Wang, Jitao Liu, Xiaoqiang Li
IET Computer Vision, 2022

Point clouds captured by LiDAR are often colorless; PCCN-RE enables high-quality colorization with a relevance embedding module built on a Conditional GAN.

Scientific Project

Neuron
A Unified Framework for Unsupervised Sparse-to-dense Brain Image Generation and Neural Circuit Reconstruction

Understanding morphology and distribution of neurons remains a significant challenge in modern neuroscience. We aim to develop a unified framework for sparse-to-dense neural generation and unsupervised segmentation, providing deeper insights into neural activity and connectivity.
