Finally, I am at the airport waiting for the plane to Beijing, and tomorrow, the plane to Seoul. I will spend next week at the ISME15 conference, which will be awesome. I hope to meet as many of you there as possible!

(And on a side note, if I don’t answer mails it might be due to that the conference wifi might be overcrowded. They warned us about this potential shortcoming of the conference center…)

So I finally have finalized my own program for what I’m going to see at ISME today and tomorrow. As the last time, the things I think I will actually attend have bold times. Generally, thursday is easy – I will be at the Bioinformatics session, where I will also present myself (at 13.30 in Hall A1). Friday is a little bit trickier, but considerably less complicated to choose from than tuesday was. See you around, and don’t forget to visit my poster (board 002A)!

I have tried to put together a list of talks I find interesting at ISME14 next week (oh, well going through the program book I find virtually all talks interesting, but some of them more so than others). I didn’t get there quite yet, but I have a list for monday and tuesday. I have realized that monday morning will likely run smoothly (a tough call between von Mering and Gilbert at 11.30, but otherwise the choices were not too hard). Monday afternoon I will probably spend in Session Room B3, where the Microbial Community Diversity: 16S and Beyond session will take place (many sessions have really silly, non-informative, names at this conference – what would not fit into the concept “16S and beyond“?). I will really miss the talk by Otto X. Cordero on bacteria act as socially cohesive units and antibiotic resistance, but I simply don’t think there will be time for a trip to Hall A2 and back just for that talk.

Tuesday is a lot messier, and can not have been planned with my interests in mind. Everything seems to happen at once here. I guess I will spend the morning discussing Mobility of genes and the species concept in Auditorium 12, but then I’ll be missing out talks on dormancy and genes under selection pressure I really would have liked to hear. But it gets even worse in the afternoon. Here I would really have needed Hermione’s time-turner. I’ll try to start the afternoon with Effects of loss of rare microbes on soil ecosystem services by Gera Hol in Auditorium 10, but will then miss at least two other diversity talks. Then, I will largely prioritize the Auditorium 12 talks on mobility of genes, with a small trip to Hall A2, where Kristian Koefoed Brandt will discuss antibiotic and metal resistance. Sadly, I will miss so many important talks this afternoon.

Another tough call is the round table discussions on Monday evening. Here, however, I feel that I have a duty to attend to the Unraveling the bacterial mobilome: Potentials and limitations of the present methodology session in Auditorium 11, which also might be the most relevant one for my current research projects.

Below you find my list of interesting talks at ISME14, sorted by time. Times in bold are the ones I will aim to attend in case I have to make a choice. Also, of course I will attend my own poster presentation on Monday afternoon (poster board number 267A). Hope to see you there!

I am on my way to Copenhagen for the ISME14 conference that begins today. I’m myself quite excited about this event, and will present three posters (two as first author), and give a short talk on antibiotic resistance gene identification and metagenomics. My talk will be in the Bioinformatics in Microbial Ecology session on Thursday afternoon (at 13.30).

If you’d like to talk about Metaxa and Megraft, I will present an SSU-oriented poster in the Monday afternoon poster section (board number 267A). My antibiotic resistance gene poster will be presented on Thursday afternoon (board number 002A), and I really encourage everyone interested in metagenomics (especially metagenomic assembly) to come talk to me then! Finally, I am also partially responsible for a poster on periphyton metagenomics with Martin Eriksson as its main author. This poster is also presented on Monday, in the Microbial Dispersion and Biogeography session (board number 021A).

I hope to be able to make another post later tonight on what are the “essential” sessions for me on this conference. Hope to see you there soon!
