I apply ecological theory to microbiome research. I am specifically interested in microbiome dynamics and how it determines microbiome structure, stability and functionality—ultimately affecting health and disease of the host. I take a holistic approach to study interactions between complex assemblages of microbes associated to multiple host species through time and space. This approach is highly integrative, combining disciplines such as community ecology and network theory, microbiology and evolutionary biology. In addition, in order to move microbiome research beyond its current descriptive phase, I have, together with statisticians, developed Bayesian models which are able to discern among multiple patterns and identifying processes. I possess good statistical and bioinformatics knowledge, including programmingin R, Python, SQL and BUGS/JAGS. I am used to working on large,complex datasets.
The key findings of my PhD thesis include:
- Host lifestyle determines community structure across large spatial scales.
- Microbe-sponge interactions are extremely diverse yet highly specialized.
- Community stability is determined by host lifestyle.
- The core microbiome promotes stability & functionality in High Microbial Abundance.
