Paul R Johnston

Postdoc, Rolff Lab/Berlin Center for Genomics in Biodiversity.


I'm a postdoc in Jens Rolff's Evolutionary Biology group at the Free University of Berlin and the Berlin Center for Genomics in Biodiversity Research

I'm interested in host-microbe interactions especially the evolution of bacterial resistance to host defences, genomics of gut symbionts, and the consequences of dynamic developmental processes such as metamorphosis for symbiosis.
