## Key Contributions

1. **Dwarf Galaxy AGN Census**: Conducted the first systematic census of active supermassive black holes in dwarf galaxies using the RESOLVE and ECO surveys. Discovered that AGN in dwarf galaxies are 5-10x more common than previously estimated. Published in The Astrophysical Journal (2022). Ranked in the 98th percentile (top 2%) of all research outputs by Altmetric. Covered by media in 18 countries and 14 languages.

2. **NASA ADS & SciX Platform**: Engineers data infrastructure and ML systems for NASA's Astrophysics Data System — a platform indexing 30M+ records and serving 10M+ researchers worldwide. Works on ML relevance ranking, semantic search, and product strategy.

3. **AstroCoder**: Core developer of AstroCoder, an AI-powered documentation system covering 2,270+ astronomy GitHub repositories.

4. **Pathfinder**: Contributor to Pathfinder, an ML-powered literature review framework that uses semantic search over 385,000+ astronomical papers. Published in The Astrophysical Journal Supplement Series (2024).

5. **Emission-Line Diagnostics**: Developed optimized optical and mid-IR diagnostic methods for identifying AGN in low-metallicity environments, providing tools for JWST observations of intermediate-mass black holes.
