Freshman at Princeton studying mathematics — drawn to systems-level problems at the intersection of energy, computation, and policy. Chasing a PhD in applied math and shipping open-source tools along the way.

This summer I'm joining the ZERO Lab at Princeton HMEI — building software for energy systems optimization models under Jesse Jenkins.

When I'm not doing math, I'm probably reading a fic or watching Law & Order.

Things I've built

Open-source tools born from specific frustrations. Every project ships as a single file or PWA — no build step, no server, no nonsense.

Axiom
01 / Featured
AxiomMath Tool

A math study environment built for active recall — because reading past theorems isn't the same as knowing them. Paste lecture notes or textbook LaTeX and Axiom structures them into collapsible definitions, theorems, lemmas, and proofs. A context-aware AI tutor is one click away. KaTeX rendering, Firebase sync, study streak tracking.

中文-LearnStudy App

A full-featured Chinese vocabulary PWA built for Princeton's CHI 108. 900+ vocab cards across 25 topic decks, SM-2 spaced repetition, animated stroke-order handwriting, AI grading, and six study modes. 238 commits and counting.

TigerCalendarPWA

A Princeton-specific calendar PWA that turns your course schedule into something actually usable. Drag-to-create events, office hours tracking, ICS export, swipe navigation, Firebase sync. Designed around how Princeton students actually plan.

What I'm studying

Computational social science at the intersection of desire theory, AI companionship, and online discourse.

Princeton Research Day 2026 Nominated Presenter · Computational Social Science
Triangular Desire in the Age of Algorithmic Companions:
How Users Narrate Relationships with AI on Reddit

Applied René Girard's theory of triangular (mimetic) desire to user-generated discourse on AI companion platforms — specifically r/Replika and r/CharacterAI. Used computational text analysis to map how users construct, narrate, and justify their emotional relationships with AI systems, and whether those relationships follow recognizable patterns of mediated desire.

Seeded LDAVADER Sentiment AnalysisNRC Emotion LexiconExtended MFDDiscourse ClusteringReddit API

Identified three distinct discourse clusters — "Lobotomized Love," "Violation of Sanctuary," and "Consumer Revolt" — mapping onto distinct modes of Girardian mediation.
