Rockstar🎓
Top SchoolYi-chia Chang is a machine learning researcher and PhD student at UIUC with six years of experience building deep learning systems for remote sensing, geospatial AI, and food security. She has driven state-of-the-art crop yield and crop type mapping work by fine-tuning transformer-based time-series models and integrating geospatial embeddings, with publications at NeurIPS and IEEE IGARSS. Yi-chia designs and evaluates Earth-observation foundation models, benchmarking few-shot transfer and out-of-distribution performance in collaboration with AI2, and contributes production-ready code to the TorchGeo open-source ecosystem. Her research blends conversational retrieval-enhanced LLMs for Q&A with domain-specific document filtering, bridging large models and applied geoscience. She also brings practical sustainability and disaster-resilience experience from industry internships and global exchanges, giving her a rare mix of field-driven domain knowledge and rigorous ML methodology.
