Research

Causal inference, precision medicine, clinical AI, and microbiome science.

My group develops rigorous and practical statistical approaches for complex health data—especially when decisions must generalize, remain interpretable, and work fairly across populations.

01

Causal inference & generalization

Methods that transport evidence across studies and populations, balance complex covariates, and learn treatment policies under real-world constraints.

  • Evidence transportability
  • Distributional balance
  • Treatment effect heterogeneity
02

Precision medicine

Interpretable decision rules for choosing treatments and doses while accounting for fairness, uncertainty, and multiple clinical outcomes.

  • Individualized treatment rules
  • Optimal dosing
  • Equitable decision support
03

Clinical AI & informatics

Auditable language models and multimodal prediction systems that remain robust across time, care settings, and patient populations.

  • Clinical language models
  • Multimodal learning
  • Model calibration
04

Microbiome & multi-omics

Scalable statistical methods for association, mediation, clustering, and meta-analysis in microbial and host-genetic studies.

  • Microbiome association
  • Host genetics
  • Cross-study discovery
