Please share this with anyone who may be interested in a post-doc in Germany: jobs.awi.de/Vacancies/20... This is quite an exciting opportunity to push the boundaries of what is known regarding the molecular basis of the formation and demise of photosymbiotic relationships in marine habitats.

I just wanted to send a quick update and thank the 70+ people who applied for the upcoming #anvio workshop and ECR symposium in Oldenburg so far. We are very encouraged with the geographical diversity, which has been one of our main concerns. The applications are open until January 10.
