I am the founder and CEO of Traustia, a company building independent validation for biomedical prediction claims, and a Doctor of Technology (D.Tech.) candidate at Purdue University. I hold an A.L.M. in Data Science from Harvard Extension School, an M.S. in Mathematics and an M.A. in Mathematics Education from California State University, Los Angeles, and graduate preparation in financial engineering.
My research is on a single question: how much confidence a quantitative result actually deserves. It centers on leakage-aware validation — the methods that keep a model from being scored on information it should never have seen — together with uncertainty quantification, calibration, and reproducible analytical workflows.
Much of this is inherited from quantitative finance, a field that learned early and expensively that a backtest is not a result. Walk-forward validation and strict timing rules exist there because it is remarkably easy to build a model that predicts the past. Biomedicine is now confronting the same failure under a different name: data leakage.
I have taught mathematics, statistics, data science, and information security at California State University, Los Angeles since 2012. I care about work that is transparent, rigorous, and genuinely useful.

Trustworthy machine learning, biomedical evidence, and decision-oriented risk — united by leakage-aware validation, reproducibility, and clear communication of uncertainty.
Leakage-aware validation, secure data workflows, responsible AI evaluation, uncertainty communication, and simulation-based validation.
Research on public omics classification, dataset integrity, leakage-aware evaluation, and the limits of translational claims.
Financial and operational risk, calibration assessment, VaR and Expected Shortfall, EVT/GPD tail-risk, and volatility-managed decision systems.
Cybersecurity risk frameworks (NIST CSF, AI RMF, OWASP), AI-enabled threats, security analytics, and algorithmic risk mitigation.
Linking public regulatory records for emissions and vehicle-safety early-warning modeling under strict temporal validation.
Curriculum design, quantitative reasoning, and pedagogy that makes statistical thinking transparent and durable.
Adjunct Instructor, Mathematics · Statistics · Data Science · Cybersecurity · California State University, Los Angeles · 2012 – present
I teach undergraduate courses spanning statistics, regression, introductory data science, quantitative reasoning, information security, and security risk management. I design applied assignments and assessments that connect data interpretation, quantitative modeling, cybersecurity concepts, risk awareness, and responsible technology use — and mentor students in reproducible analysis habits and security-aware pathways.
I also coordinate the 2026 Summer Biomedical Engineering & Quantum Technology Program at UCLA, supporting interdisciplinary research preparation across biomedical engineering, emerging technology, and quantitative reasoning.
Earlier in my career, I taught mathematics at Tianmu Junior High School in Taipei, Taiwan.
A selection of public data-science and machine-learning projects — spanning causal inference, computer vision, finance, and NLP.
