Hi! We are looking for a PhD to work on the cross talk between transposable elements, insects and intracellular bacteria on the bioinformatics side. The PhD would be supervised by @mariefablet.bsky.social and myself along with @nicolasparisot.bsky.social Deadline December 2025! Please share! #tesky
