About me

Educational software • applied cryptography • privacy-preserving computation

  • I am an undergraduate at the University of Notre Dame, majoring in Computer Science in the College of Engineering with a supplementary major in Mathematics for Engineers (B.S. expected May 2027).
  • I am a research assistant in the Data Security and Privacy Lab (DSP-Lab), advised by Prof. Taeho Jung, where I work on privacy-preserving computation over encrypted data — private set intersection, private membership testing, and private stream aggregation under fully homomorphic encryption (FHE).
  • My research interests are in applied and lattice-based cryptography: homomorphic encryption (BFV / FHE), secure multiparty computation, and formal verification for quantum algorithms with applications to post-quantum cryptography.
  • Since summer 2025 I have been part of the DREU (Distributed Research Experiences for Undergraduates) program in Quantum Information Science at UMBC, advised by Prof. Lei Zhang, developing hybridized formal-verification models for quantum algorithms.
  • I build software for learning and private communication: PathThruMath, Lectio, and pqmsg.

Software projects

  • PathThruMath — an interactive map of mathematical concepts, searchable textbooks, hover definitions, and personalized study plans.
  • Lectio — language learning through real texts, aligned translations, contextual dictionary lookup, vocabulary review, and grammar practice.
  • pqmsg — a cross-platform desktop messaging prototype with post-quantum end-to-end encryption and multi-device delivery.

Research experience

Data Security and Privacy Lab, University of Notre Dame Aug 2024 – present · Advisor: Prof. Taeho Jung

  • DFPSI: Decoupled Fuzzy Private Set Intersection (submitted; 3rd author) — benchmarked quantized cosine similarity under BFV for biometric and financial data in collaboration with deep-learning models; authored the experimentation and evaluation; optimized latency and parameter choices.
  • Scalable Private Membership Test over Distributed and Encrypted Data (3rd author) — built latency experiments for encrypted multi-server queries under FHE and tuned parameters for scale; applications to fraud detection and no-fly / watch-list screening.
  • SLAP correction (2nd author) — corrected the security proof in SLAP, a secure multiparty protocol for private stream aggregation.
