Identifying clinically actionable features that display differential abundance and expression patterns across experimental conditions is an important first step toward characterizing the multi-omics landscape of complex human diseases. The field of multi-omics, however, has not yet reached the maturity attained in other established molecular epidemiology fields such as cancer biomarker discovery and genome-wide association studies with best practices and centralized resources remaining scarce. This is challenging because many standard single-omics analysis methods cannot be directly applied to multi-omics data without falling prey to false positive or false negative results and realistically complex yet flexible modeling techniques must be developed to adequately reflect the biology.

In this talk, I will focus on statistical modeling for multi-omics classification and regression including methods for differential analysis, batch effect correction, and machine learning models to enable better disease outcome prediction and patient stratification.

I will discuss recently developed statistical methods ranging from Bayesian ensemble methods to sparse graphical models as well as self-adaptive models that adapt to the underlying technological variability in multi-omics data while improving upon state-of-the-art single-omics analysis methods.

Lastly, I will conclude with comments on the promises and implications of scalable Bayes for large-scale multi-omics data integration and inference for translational epidemiology studies and provide some empirical evidence of using multi-omics both as a multi-purpose biomarker and potential therapeutic target in precision medicine. All these approaches will be illustrated on data arising through various multi-omics and single-omics public datasets including the integrative Human Microbiome Project.
