About

I’m Kyle (Yilin) Gao, a Postdoctoral Fellow in Systems Design Engineering at the University of Waterloo. I completed my PhD in Systems Design Engineering at the University of Waterloo in May 2025. I have a background in mathematical physics from my undergraduate and master’s studies.

My research focuses on large-scale 3D geospatial modeling, urban digital twins, and multimodal analysis for environmental monitoring and disaster assessment. I also have work in multiple areas of remote sensing, geoinformatics, and geoAI.

I’ve authored and co-authored over fourty 9 peer-reviewed papers (nine first-authorships), including publications in IEEE Transactions on Geoscience and Remote Sensing and the ISPRS Journal of Photogrammetry and Remote Sensing. My current work focuses on building intelligent, multimodal systems for remote sensing that integrate geospatial data, visual analysis, language for applications in both urban digital twins and environmental management.

Recent Highlights

May 2026 — CVPR 2026 Workshops

We are pleased to share that two of our works have been accepted to CVPR 2026 workshops, where we will present preliminary results.

Workshop Presentation CVPR 2026: Workshop on Foundation and Large Vision Models in Remote Sensing
Title: BuildingTwin: Geometrically Grounded Building-Centric 3D Reconstruction for Urban Digital Twins

Workshop Paper: CVPR 2026: MetaFood Workshop
Title: KitchenTwin: Semantically and Geometrically Grounded 3D Kitchen Digital Twins

Both works explore geometrically grounded and semantically consistent 3D reconstruction for digital twin applications.
