The 41st annual meeting of the DGP [summer edition] is appraoching.

12.-15. July, Kardinal Schulte Haus, Bergisch Gladbach

We warmly welcome you to the 41st annual conference of the DGP. Due to the Covid pandemic, the meeting will take place exceptionally in summer. We hope to be able to meet again in person and discuss science, research and much more.

Thanks to the numerous sponsors, there will be reduced fees for 25 students and doctoral students: the only requirement is the active contribution in the form of a poster or a lecture.

Likewise, Tuesday’s workshop on RNAseq will be free of charge for the first 40 undergraduate and graduate students who register. Postdocs only pay the subsistence costs. The workshop will give an introduction to all aspects of RNA seq, starting with the isolation of long and short RNA, the various methods of library preparation, the function and specification of the sequencing platform and an introduction to bioinformatics principles.

The conference includes a special session on the subject of endosymbiosis, an exciting area that is making great strides in many respects. We invite you to lectures in this area. Of course, all other topics of the DGP are represented at the conference, from morphology to diversity to genetics.

We hope to see everyone in Bergisch Gladbach in July. The hotel is easily accessible both by public transport and by car and offers us an ideal conference environment.
