Presentation
My area of expertise is the study of microbial ecosystems using metagenomics, metatranscriptomics and 16S rRNA gene profiling. I have worked in several settings (deep-subsurface, acidic rivers, ocean, lakes...), and I strive to find common patterns in the way that microorganisms interact between themselves and with the environment.
To achieve this, I apply (and if necessary, develop) bioinformatics methods in order to integrate the vast amount of information generated by modern approaches (large-scale spatial and temporal series comprised of functional, taxonomic and physicochemical profiles) and form a coherent picture of what drives the behaviour of the community. Ultimately, I want to find interesting and hopefully useful stories about how microbes and ecosystems work.
Research
At SLU, I study the diversification trajectories of freshwater microorganisms, their relationship with environmental constraints, and the internal structure of the resulting microbial species.
Are freshwater microbial species delimited by well-defined boundaries, or is there a fuzzy continuum of genotypes capable of exchanging genetic information? Do phylogenetically unrelated microorganisms follow parallel diversification trajectories when subjected to similar pressures? Does this diversification lead to an increase in community stability? I aim to answer these questions by combining metagenomics, metatranscriptomics and enrichment cultures over a set of more than 200 lake samples, and studying the dynamics of individual genomes in space, time, and over the niche landscape.
