I was privileged to get to sysadmin for a pioneer microbiologist-geneticist whose passion was the microbiome. Not long before I left, I started seeing indicators that the the microbiome(s) in us and that we encounter and how they interact is vastly more important than we have realized. From this biofilms have made advances, etc. With sequencing getting so much cheaper, the research opportunities are just sitting around waiting, and are the kind that offer real and tangible results.
