Longitudinal cohorts
Repeated wearable, home-monitoring, or Apple Health-compatible data paired with clinical biomarkers or outcomes.
Methods & biostatistics
Calibration, sensitivity analysis, missing-data strategy, temporal mediation, within-person modeling, subgroup performance, and uncertainty communication.
Adaptive personalization & privacy-preserving ML
Longitudinal modeling, on-device learning, individualized calibration, federated learning, secure aggregation, privacy-preserving machine learning, and digital-biomarker methods that can test whether downstream personalization adds reproducible value beyond the locked deterministic BioMIR baseline without centralizing raw longitudinal health records.
AI evaluation & semantic health interfaces
Canonical scientific knowledge representation, typed semantic APIs, tool-calling fidelity, provenance-linked explanation, on-device language-model evaluation, voice and narration, App Intents/Siri-facing interaction, hallucination testing, privacy/data minimization, and human-factors methods for constrained conversational health intelligence.
Clinical and epidemiologic validation
Cardiometabolic prevention, aging research, longitudinal physiology, digital biomarkers, and pragmatic interpretation of multi-timescale health data.
Exploratory model-derived analytics
Prospectively specified evaluation of BioMIR outputs as exploratory longitudinal analytics or protocol-defined endpoints where appropriate. Adaptive BioAge should not be represented as a validated surrogate or evidence of treatment benefit without fit-for-purpose validation.
Human factors
Testing whether contributor-level explanations and data-quality signals improve understanding without creating false precision or inappropriate clinical inference.
Study governance
Lock or explicitly version the algorithm, reference data, parameter sets, and software for a study, and prespecify provenance, access, consent or ethics review, analysis responsibilities, publication policy, and permitted reuse before nonpublic participant-level data are exchanged.
