- WV-Net SAR foundation model: Built end-to-end data and training pipeline for 12M+ satellite images spanning 9 years of global coverage; achieved 90%+ mAP on rare-pattern retrieval and up to 40% improvement on downstream classification and regression tasks. Published in AMS AI for Earth Systems (2025).
- DXA healthcare foundation model: Engineered a domain-informed self-supervised embedding model consolidating four NIH longitudinal cohorts; outperformed the WHO clinical hip-fracture risk tool by 10% and enabled mortality prediction. Published in Communications Medicine (2022).
- Solar atmosphere inversion model: Developed ML model for inverse solar physics trained on terabyte-scale simulation data; deployed into the Daniel K. Inouye Solar Telescope production workflow with sim-to-real monitoring. Published in The Astrophysical Journal (2024).
- Diffusion-based weather forecasting: Built score-based diffusion downscaling pipeline improving speed, accuracy, and resolution of probabilistic solar and climate forecasts.
- Additional ML systems: Physics-informed Belle-II particle identification (97% accuracy); tree-structured GNN for microbiome analysis (+30% over baselines); custom pose-estimation pipeline for evolutionary biology lab cutting video analysis time by 95%, from hours to seconds.
