The functioning of the human body constitutes a complex interplay of human processes and “services” rendered to us by the 1,000 trillion microbial cells we carry. Disruption of this natural microbial flora is linked to infection, autoimmune diseases and cancer, but detailed knowledge about our microbial component remains scarce. Recent technological advances such as metagenomics and next-generation sequencing make it possible, for the first time, to study the various microbiota of the human body at a previously unseen scale. These advances have allowed the initiation of the International Human Microbiome Project, aiming at genomically characterizing the totality of human-associated micro-organisms (the “microbiome”).
However, the complexity of metagenomic datasets makes their analysis a major bottleneck. This allowed the birth of a new, exciting subfield in computational biology which will eventually allow classical, cellular-level systems biology to progress towards modeling entire communities (“ecosystems biology”) and untangling interspecies networks of competition, collaboration and communication at the molecular level.
The Raes lab combines large-scale, next-generation sequencing with novel computational approaches to investigate the functioning and variability of the healthy human microbiome at the systems level and study its alteration in disease. In this context, we recently discovered the existence of discrete gut flora types (enterotypes), that are independent of host properties such as nationality, sex or race and are studying the predictive power of microbial markers for various intestinal diseases. In addition, we focus on the development of computational methods for the analysis of (next-generation) sequence data and the investigation of community properties from metagenomics,  metatranscriptomics and meta-metabolomics data, which are applied in a wide range of environments (ocean, soil, etc.).

Count your blessings: Quantitative Microbiome Profiling

15/11/2017 - Wen it comes to the bacterial content of your bowels and how it relates to your health, not only percentages matter, but also numbers count. That is at least one of the main messages of the latest research of Jeroen Raes (VIB-KU Leuven) and his team.

Aphea.Bio aims at leading position in next generation agricultural biologicals

16/06/2017 - VIB, Ghent University and KU Leuven have launched a new spin-off: Aphea.Bio. This new company will develop sustainable agricultural products based on natural microorganisms to increase crop yields and to protect them against specific fungal diseases.

The Flemish Gut Flora Project Is Flourishing

26/08/2016 - ​Did you know that one of the world’s largest gut microbiome research efforts is run by a VIB lab? Jeroen Raes and his team started a bottom-up initiative in 2012 that would soon turn out to be a huge research project

Unraveling the food web in your gut

13/06/2016 - Using a manually curated metabolic module framework for (meta-)genomic data analysis, Sara Vieira-Silva, Gwen Falony and colleagues from the Jeroen Raes lab (VIB/KU Leuven) studied species-function relationships in gut microbial genomes and microbiomes.
