I am a student researcher and builder working across natural language processing, computational economics, and human-centered AI.

My research examines how intelligent systems represent language and how they reshape labor markets. Through LinkScape, I also build technical and educational projects intended to make AI more useful outside the laboratory.

CNM-BERT — A structural Chinese language model that represents characters through their internal ideographic composition, injecting discrete sub-character structure into BERT at the embedding interface. On out-of-vocabulary characters it improves structural probing accuracy by +9.8 points over the strongest baseline, while matching or exceeding comparable Chinese PLMs on CLUE. Co-first author (equal contribution); manuscript submitted to ACL Rolling Review 2027.

AIFE Engine — An NLP and econometric research pipeline studying firm-level AI adoption and labor demand from online job postings. A knowledge-distillation pipeline turns unstructured hiring text into a firm–year panel of AI intensity and task composition, which then feeds causal and forecasting analysis. The repository holds the measurement stage: corpus extraction, entity resolution, teacher scoring, and index construction. Co-authored with Yintong Chen and Zichun Qiu; Regeneron ISEF 2026.

PoliScope — A source-grounded legislative intelligence platform. A LangGraph RAG orchestrator traces bill evolution, sponsorship, lobbying disclosures, and campaign finance across the Congress.gov, GovInfo, Senate LDA, and OpenFEC APIs, grounding every answer in a primary government source. Built at HackHarvard 2025.

AI Digest — A self-hosted research and industry intelligence system: retrieval, clustering, personalization, evaluation, and multi-channel delivery. Runs on a daily schedule against live academic, industry, and community sources, with a deterministic mock-LLM mode so the whole pipeline is reproducible without credentials.

Resonaite — An experimental adaptive-audio platform combining AI-generated music, real-time digital signal processing, and closed-loop EEG feedback. A research prototype, not a medical device.
