So, last week I started my Ph.D. in Joakim Larsson’s group at the Sahlgrenska Academy. While I am very happy about how things have evolved, I will also miss the ecotox group and the functional genomics group a lot (though both do their research within 10 minutes walking distance from my new place…) I spent last week getting through the usual administrative hassle; getting keys and cards, signing papers, installing bioinformatics software on my new monster of a computer etc. Slowly, the new room starts to feel like it is mine (after nailing phylogenetic trees, my favorite map of the amino acids, and my remember-why-Cytoscape-visualisation-might-not-be-a-good-idea-for-all-network-like-structures poster to the billboard).
So what will this change of positions mean? Will I quit doing research on microbial communities? Of course not! In my new position, my subject of investigation will be bacterial communities subjected to antibiotics. We will look for resistance genes in such communities, and try to answer questions like: How do a high antibiotic selection pressure affect abundance of resistance genes and mobile elements that could facilitate their transfer between bacteria? Can resistance genes found in environmental bacteria be transferred to the microbes of the human gut? Can the environmental bacteria tell us what resistance genes that will be present in clinical situations in the near future? All these questions could, at least partially, be answered by metagenomic approaches and good bioinformatics tools, and my role will be to come up with the solutions provide answers to them.
I am excited over this new project, which involves my favorite subject – metagenomics and community analysis – as well as important factors, such as the clinical connections, the possibility to add pieces to the antibiotic resistance puzzle, and the role of gene and species transfer in resistance development. I also like the fact that I will need to handle high-throughput sequence data, meaning that there will be many opportunities to develop tools, a task I highly enjoy. I think the next couple of years will be an exciting time.
