Research taught me to treat reproducibility as infrastructure.

100+global researchersusing the platform
8biomarker candidatesfrom multi-omics analyses
3manuscripts in reviewlead-author, under review
  1. Biological samplesRaw specimens, assays, observations
  2. IngestionCollect & record data at scale
  3. ValidationQuality checks, controls, provenance
  4. ModelsAnalyze, learn, test
  5. Reproducible artifactsNotebooks, code, data packages, reports
  6. Production patternsPipelines, APIs, platforms, monitoring

Reproducibility checklist
  • Version control for code & configs
  • Immutable raw data storage
  • Documented protocols & parameters
  • Deterministic environments
  • Automated validation & QC
  • Re-runnable pipelines (idempotent)
  • Provenance captured end-to-end
  • Shareable artifacts & reports
  • Peer review & independent verification
