We celebrated our 5th anniversary of the Let's Talk About Symbiosis Workshop on January 25, 2018. The invited speaker was Prof. Ehab Abouheif from the MacGill University, Canada, a distinguished expert in evolutionary developmental biology, with the topic "Obligate endosymbiosis in ants reveals developmental steps to major evolutionary transitions". Eight PhDs and Postdocs from the three departments Ecogenomics and Systems Biology, Limnology and Bio-Oceanography and Microbiology and Ecosystem Science presented their current research, followed by a discussion round Let's Talk About Us on visions for strengthening and improvements. The workshop ended with an informal get together.
