Quantitative Research | Machine Learning | Data Science
I am an applied data scientist and quantitative researcher with an M.S. in Applied Data Science from the University of Southern California and a B.S. in Statistics and Data Science from the University of California, Santa Barbara.
I currently research systematic equity signals as a WorldQuant BRAIN Research Consultant. My interests sit at the intersection of statistical modeling, machine learning, financial markets, and reproducible research.
I have engaged in independent discretionary options trading since October 2024, with a focus on volatility, option pricing, Greeks, position construction, and risk management.

Derivatives Pricing & Risk
End-to-end chain from market quotes to a risk number: a 40-year SOFR OIS curve bootstrapped from SR3 futures and swaps under exact market conventions, a SABR calibration of the SPY implied-volatility surface with static-arbitrage diagnostics, Greek P&L attribution on an eight-leg option book with FRTB PLA testing, and a VaR/ES and stress-testing framework documented to SR 11-7. Second-order Greek terms cut unexplained P&L by 87.6%; the validation report states the framework's failures alongside its results. -
Alpha Research Orchestrator
Offline-first, evidence-gated research engine for WorldQuant BRAIN alpha research. A SQLite ledger records every candidate's identity, state transitions, and gate decisions, so every surviving alpha is reconstructable and auditable rather than a black box; deterministic code owns validation, routing, and limits, while an LLM can only propose. Ships a CLI and a local MCP server — no submission capability, every candidate stops at human review. Built on this pipeline: 36 equity alphas for WorldQuant IQC 2026, finishing 578th of 152,452 participants globally (top 0.4%). -
IMC Prosperity 4 Review
Reconstructed and evaluated trading strategies across market making, options, auctions, and multi-asset relative value using market replay, order reconciliation, and P&L attribution.

Audio Event Detection and Notification System
Group project integrating mobile audio collection, AWS EC2, SageMaker inference, and automated alerts. I was responsible for data preprocessing and model training. -
Hybrid Recommendation System
Built a PySpark-based rating prediction pipeline combining collaborative filtering with XGBoost and gradient-boosting models using user, business, check-in, photo, and interaction features. -
Two-Stage Recommender, Bandit & A/B Evaluation
Extends the recommender above into a full ranking system: CF retrieval → LambdaMART learning-to-rank → LinUCB contextual-bandit re-ranking → offline A/B evaluation. On the real 455K-rating Yelp dataset, item-CF retrieval beats a popularity baseline by 3.8x NDCG@10; the A/B harness adds CUPED variance reduction and always-valid (mSPRT) significance testing. -
Credit Portfolio Analytics
End-to-end consumer-credit case study: SQL portfolio analytics, a PD model (logistic regression + XGBoost, AUC 0.767) with a fair-lending disparate-impact check, decile-level risk-return pricing, and KMeans customer segmentation, delivered as a dashboard and a one-page executive summary. Declining or repricing the riskiest 40% of the book lifts modeled portfolio profit by 184%.
