🚨 Postdoctoral Opportunity for Female Scientists🚨 The University of Vienna is awarding at least 20 fully funded 4 year postdoctoral positions to outstanding female scientists Interested? Get in touch via direct message careers.univie.ac.at/en/postdoc/e... #MicroSky 🧪 #PostDoc @univie.ac.at - Check out this awesome resource for all your future microbial #genome analyses: #GlobDB is the to date most complete genome database available! Developed by @daanspeth.bsky.social and colleagues 🧪🦠🧬🖥️
- Our paper describing the GlobDB is now published in @bioinfoadv.bsky.social doi.org/10.1093/bioa... The GlobDB is the largest species dereplicated genome database currently available, containing 306,260 species representatives. More information on globdb.org 1/5 🖥️🧬🦠
