I turn scientific models into reproducible systems and public tools.

A public HIV-modeling platform spanning the interactive product, model-execution workflows, versioned simulation data, and cloud delivery. I designed the system and implemented its frontend, orchestration, and integration layers.

• +31-metro and multi-state policy analyses
• +One model configuration drives workflows and frontend behavior
• +On-demand model runs with cached, shareable results
• +Reusable orchestration cut workflow code by 54%

The execution layer behind JHEEM: reproducible R model images, versioned simulation artifacts, numerical regression checks, and production-safe release workflows. I am currently consolidating five container repositories into a history-preserving monorepo with path-aware matrix CI.

• +180GB+ of versioned simulation artifacts
• +Four model images reproduce production outputs bit-for-bit
• +Digest-pinned base image and renv-locked dependencies
• +Monorepo migration preserves image names and production pins

First-author research developing a generative, patient-specific model of infant microbiome dynamics to forecast ecosystem trajectories and identify early signals associated with neurodevelopmental risk.

• +Published in Science Advances in 2024
• +88 preterm infants and 398 longitudinal samples
• +Forecasted microbial abundance dynamics with R² = 0.69
• +Open-source qbiome research implementation

An active HIV intervention-modeling study in JHEEM. I designed the intervention lifecycle, built the calibrated analysis and verification pipeline, and used decomposition and sensitivity analysis to distinguish structural limits from implementation assumptions.

• +Mechanistic compartment and transition design
• +Calibrated multi-simulation analysis with provenance
• +Structural, directional, and base-preservation verification
• +First-author manuscript work in progress

The public web presence for a Johns Hopkins modeling group, including an interactive application for exploring country-level HIV aging projections and the evidence behind them.

• +Data-driven country projection explorer
• +Research findings and publications presented for mixed audiences
