Science for Life Laboratories (SciLifeLab) in Stockholm will host a metagenome data analysis workshop on May 21-23, in which I will participate as a tutorial assistant. Additionally, our group leader Joakim Larsson will be giving a lecture about how we use metagenomics to assess the environmental reservoir of antibiotic resistance genes (much of my recent work will likely go into that). I hope to meet you there, so don’t forget to register!

Confirmed speakers:
Lex Nederbragt, Oslo University, Norway
Saskia Smits, Erasmus University Rotterdam, Netherlands
Joakim Larsson, Göteborg University, Sweden
Paul Wilmes, University of Luxembourg, Luxembourg
Anders Andersson, SciLifeLab, Sweden
Noan Le Bescot, UPMC (Tara expedition), France

The workshop is part of the AllBio Bioinformatics initiative.

If you are thinking about doing a PhD and think that bioinformatics and antibiotic resistance is a cool subject, then now is your chance to come and join us for the next four years! There is a PhD position open i Joakim Larsson’s group, which means that if you get the job you will work with me, Joakim Larsson, Erik Kristiansson, Ørjan Samuelsen and Carl-Fredrik Flach on a super-interesting project relating to discovery of novel beta-lactamase genes (NoCURE). The project aims to better understand where, how and under what circumstances these genetic transfer events take place, in order to provide opportunities to limit or delay resistance development and thus increase the functional lifespan of precious antibiotics. The lion’s share of the work will be related to interpreting large-scale sequencing data generated by collaborators within the project; both genome sequencing and metagenomic data.

This is a great opportunity to prove your bioinformatics skills and use them for something urgently important. Full details about the position can be found here.

Last Friday, our research group moved into our new facilities at the Department of Infectious Diseases. I am very happy with my new room and my new view, both depicted below.

Our new affiliation is:

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.
