Together with my PhD student Sam Röttjers, I created the MOOC: "How to analyse a microbiome". I am also contributing to "Omics Techniques and Data Analysis" (B-KUL-I0V62a) at KU Leuven and to "Modeling dynamical systems in biology" (BINF-F404) at ULB. In addition, I also created an online tutorial on microbial network inference.

Roles and Memberships

I am senior editor at The ISME Journal, editor at mSystems and a board member of the Belgian Society for Microbiology. In addition, I served as a jury member in 9 Master thesis defences, 5 PhD defences and 1 habilitation.

Reviewer Activities

I reviewed articles for PNAS, ISME, Nature Communications, Microbiome, Bioinformatics, PLoS Computational Biology and mSystems among many others. Please see a summary of my reviewer activities at publons. In addition, I am regularly reviewing grant applications, including for NWO, ISF, ERC, Helmholtz and other institutions.
