Summary
🤩
Rockstar🎓
Top SchoolRitwik Gupta is a Postdoctoral Researcher and seasoned AI/ML practitioner with 12 years of experience applying computer vision and autonomy to humanitarian assistance and disaster response (HADR). He bridges academic rigor (PhD candidate at UC Berkeley, large-scale geospatial dataset and model publications) with government and industry impact—serving in technical leadership roles at the Defense Innovation Unit, advising the FBI on responsible AI, and transitioning research into operational systems. His engineering work spans open-source contributions to notable projects like Microsoft’s TorchGeo (adding remote-sensing indices such as NBR/NDBI) and platform-level fixes in Swift Package Manager, reflecting both domain expertise and cross-platform systems sensibility. He combines hands-on model and software development with policy-minded stewardship to ensure AI is deployed ethically and effectively in high-stakes, resource-constrained environments.

TorchGeo: datasets, samplers, transforms, and pre-trained models for geospatial data
Role in this project:
ML Engineer
ML EngineerContributions:10 reviews, 5 commits, 7 PRs in 9 months
Contributions summary:Ritwik contributed to the development of geospatial data processing tools within the `microsoft/torchgeo` repository, specifically focusing on implementing and testing new indices. They added functionality for calculating and appending indices like Normalized Burn Ratio (NBR) and Normalized Difference Built-up Index (NDBI), improving the library's capabilities for remote sensing data analysis. This involved modifying existing transform modules, creating new test cases, and integrating the new indices into the project's overall structure.
