I’m Tristan.

Undergraduate Research Assistant

• Built the BD3D research viewer (Next.js, TypeScript, React Three Fiber), linking 314 scholarly annotations to 607 surface regions across 6 photogrammetric Egyptian coffin models, with two-way selection, raking-light inspection, and collection-wide search.
• Designed a compressed 3D asset pipeline (meshopt glTF, tiered textures, checksummed provenance) that cut exhibit downloads by 74% (82 MB to 21 MB across six coffins) and geometry parsing from 82–132 ms to 2–3 ms.
• Built a structured annotation data pipeline with schema validation, replacing manual XML lookup; 127 automated tests run in CI.
• Lead the incoming URAP students and the design team.

Data Research Intern

• Built an NLP retrieval system combining BM25, dense transformer embeddings, and a sentence-transformers CrossEncoder reranker over 10,000+ California K–12 district webpages and policy documents.
• Benchmarked lexical and neural retrieval on human-validated evidence (Recall@K, MRR): Recall@5 up 35%, manual source-discovery time down 76%.

Data Science Intern

• Built a model that estimates California single-family sale prices from 309K cleaned CRMLS sales (Jan 2024 – Apr 2026), adding location, property-age, and school-district features via a spatial join across 680 districts.
• Evaluated chronologically with leakage rules: the final XGBoost model reached 7.7% median error on 11,890 held-out April 2026 sales, versus 16.5% for a linear baseline.

Undergraduate Research Apprentice

• Built an automated Python photogrammetry pipeline (Agisoft Metashape API) processing 1,000+ images into 3D reconstructions, cutting manual processing time by 40% (~30 → ~18 min each).
• Developed Ridge regression models on SfM and image-overlap graph features to predict reconstruction quality: 13.7% lower geometric RMSE than a reprojection-error baseline, with leakage-aware cross-validation.

Computer Science Mentor

• Teach Python weekly to 100+ high school students.
