Infant microbiome

Infant microbiome development: an interkingdom perspective The effect of probiotics on preterm infant gut microbiome maturation Microbiome-based diagnostics

Method development for microbiome Analysis

1. Microbiome Meta-Analysis There is a growing need for knowledge synthesis about the role of microbiome in health and disease using meta-analysis as more and more microbiome studies become available. The current approaches to microbiome meta-analysis could be more accurately described as mega-analysis.

Rethinking the causal framework in microbiome research

The field of microbiome research has fundamentally changed our perception of the host-microbe interaction in maintaining health and predisposing or causing disease. While the majority of the research so far has focused on identifying association rather than elucidating causal mechanisms, the field has evolved rapidly to address these shortcomings.

Experimental evaluation of Priority Effect Hypothesis

Organ-on-chip is a novel technology harnessing advances in microengineering and fluid dynamics to reconstruct the physiological tissue microenvironment, including many features that cannot be achieved in conventional tissue culture (e.g. villi, differentiation of epithelial cell types, mucus secretion, peristalsis).
