We seek highly motivated students and postdocs to join our research group!

Our research program bridges novel statistical and ML/AI research and impactful biomedical research. Its thrust is to develop robust statistical and ML/AI methods and models for advancing precision medicine and population health, with keen interests in integration of big health data such as -omics, electronic health records (EHRs), and imaging data. We have developed responsible statistical methods and ML/AI models for (integrative) analysis of big health data (such as -omics data, electronic health records data, and imaging data), missing data, causal inference, data privacy, algorithmic fairness, Bayesian methods and clinical trials. More recently, our research has branched into LLMs, foundation models and AI agents for biomedicine. 

Our research has been supported by NIH, PCORI, NSF, ARPA-H, VA and AHA.
