About

Hey! I'm a fourth-year Computer Science and Economics student at Emory University, passionate about software engineering. My interests lie in web and game development, machine learning, and large language models. I enjoy solving real-world problems through code and am always eager to learn new technologies.

Building things that work.

Projects

01
Featured

Lumos-LLM

Forked Lumos, a published visual analytics tool, and restructured its backend from a single fixed-baseline bias metric into a real-time, per-participant system that gates LLM-generated recommendations behind a calibrated threshold.

Soundgaze

Extended a hackathon-built 3D music explorer into a deployed 8K-track point cloud with instant PCA, t-SNE, and UMAP layout switching through parallel prefetching and position tweening. Built a 578-dimensional hybrid CLAP and acoustic embedding, validated on Timbremetrics and Covers80; nearest-neighbor search uses the full space while 3D reduction drives the visual layout.

Experience

Cognition & Visualization Lab @ Emory University

Undergraduate Researcher

Cognition & Visualization Lab @ Emory University

Jan 2026 — PresentAtlanta, GA
  • —Developed a metrics pipeline that elicits a participant’s prior belief and scores each variable by dwell and selection consistency with it; redesigned triggering from one pooled per-participant score into variable-level, independently cooled triggers.
  • —Implemented Jensen–Shannon divergence variable weighting to rank bias signals across variables, and calibrated the detection threshold via percentile comparison against a Dirichlet-sampled null distribution to bound the false-positive rate.
  • —Nominated for the CRA Outstanding Undergraduate Researcher Award; second author on a CHI 2027 submission.
Cognition, Narrative, and Culture Laboratory @ Florida International University

Undergraduate Researcher

Cognition, Narrative, and Culture Laboratory @ Florida International University

Jun 2026 — Aug 2026Miami, FL
  • —Constructed a labeled tri-class dataset of 1,750 reviews spanning ACL, ARR, COLING, and CoNLL venues to train transformer-based classifiers distinguishing authentic, AI-enhanced, and AI-generated peer reviews, supporting a DeBERTa-v3 model that achieved 96.9% accuracy and 0.958 macro F1 on a held-out test set.
  • —Built a comparative evaluation of AI-text detectors against the project’s tri-class taxonomy to benchmark AI sensitivity.
