Rebecca (Shuang) Gao

AI/ML research scientist building reliable intelligent systems for noisy, multimodal physical-world data.

I work at the intersection of scientific machine learning, computer vision, probabilistic inference, Physical AI, and agentic systems.

Featured work

  • GeoWorld Studio — typed, reproducible geoscience workflows that turn structured scenarios into synthetic earth models, physical properties, reflectivity, and seismic responses.
    Engineering blog

  • SnapGraph3D — constraint-aware 3D assembly with scene graphs, validation, repair, and deterministic benchmarking.

  • JobTracker — application tracking and transparent job-skill analysis built with React, Express, Playwright, and local LLM workflows.

Research

  • SAGE-AVO: structure-aware multimodal inversion with transformers, dynamic graph learning, conditional flow matching, and physics-based loss functions.
  • TLNet: 3D/4D change detection and segmentation under sparse labels.
  • Probabilistic inference and uncertainty quantification for nonlinear inverse problems.
