For everyone anxious to see the videos of the Stanford Bioinformatics for the Microbiome Symposium (including me!), please be patient. The AV team is working hard to generate videos for each individual talk, but that will take some time. Check in at this blog under the “Jobs and Events” header where I will post them once they are ready.
