Undergraduate Research → Independent Continuation · Sep 2025–Present
Sign2Text
An iOS interface and online continuous sign-language recognition research system balancing compute, latency, and recognition quality.
- Contribution
- Led a three-student team, built the SwiftUI workflow, and independently continued research on strictly causal, budget-aware scheduling.
- Evidence
- On Phoenix-2014T dev, a frozen adaptive baseline cut processed windows by 32.6% and repeated wall time by 29.5%, with a 0.19-point WER increase.
Independent Continuation · May 2026–Present
SceneZero
An iOS spatial notebook for capturing multimodal inspiration and developing scene facts into reusable creative inputs.
- Contribution
- Independently repositioned and extended a course-originated prototype through multiple iterations.
- Evidence
- The current iOS target has a verified device build, passing unit tests, simulator launch, and a relaunch persistence smoke test.
Course–Lab Collaboration · May–Jun 2025
CHI Social Media Research Dashboard
A selective course–lab collaboration that turned 197 tagged CHI social-media papers into a linked-view dashboard.
- Contribution
- Built the Overview Panel and implemented chart-to-Sankey filtering within a three-person frontend team.
- Evidence
- Public source and deployed demo covering 197 tagged records; the project is archived.
Mentored ML Study · Feb–Mar 2024
NLP Model Comparison
A controlled comparison of classical sentiment pipelines on 4,000 IMDb movie reviews.
- Contribution
- Implemented preprocessing, model comparison, and validation-based tuning in a mentored study.
- Evidence
- TF-IDF + Logistic Regression reached 89.3% on a held-out 15% test split.
Explorations & Interests
Film, creative practice, and the experiments they lead to
Personal AI Experiment · Mar 2026–Present

Personal Practices
Music & Team Sport
I return to instruments for the pleasure of learning sound, and to football for the shared rhythm of training and moving with a team.
