Description:

The human microbiome is the community of microorganisms that reside in different body habitats. Host-microbiome interactions play an important but poorly-characterized role in health. Advances in high-throughput technologies including next-generation sequencing and mass spectroscopy allow us to query the population of micro-organisms and observe the interactions in greater detail. The effect of choices in measurement protocols, the multivariate longitudinal nature of data, and combining measurements on different scales pose difficulties in discovering and confirming significant relationships in the human microbiome.

The aim of this workshop was to create a forum for ideas for overcoming current and future challenges in the analysis of human microbiome data. In this workshop, participants learned how metagenomic (sequence-based) and metabolomic (mass spectroscopy-based) data are generated and the implications for analysis. Gaps in the current state-of-the-art methods were highlighted, particularly with respect to the analysis of multivariate longitudinal data and the use of statistical experimental design to assess bias. Participants assembled into research groups and were asked to formulate plans to address the deficiencies of current methods.

Participants could optionally submit an abstract for a short presentation or poster.  A small subset of the submitted abstracts were selected for short presentations at the workshop.
