About Jesse Noar



I'm a microbiology PhD from North Carolina State University who finds microbes continually fascinating. I'm working on ways to see just how good for us bacteria can be, and in order to share my enthusiasm for discoveries made by others or myself, I created BacterioFiles.

Back in early 2009 when science podcasts first caught my interest, I looked around to see if I could find any up-to-date podcasts that were focused on microbiology. There were a few, but they mostly seemed to focus on the negative aspects of bacteria or viruses that cause disease. I wanted news about how important bacteria and other microbes are, in our bodies, in the environment, and even in our technology, as well as how interesting and diverse they can be. So my path was clear: I had to fill the niche.

That path led to the creation of BacterioFiles, the podcast for microbe lovers, dedicated to promoting the exploration of the mostly-invisible world that is all around us.

Some bacterial species use multiple strategies within a single population to deal with environmental challenges.

Polymer-coated bacteria make really good vaccines.

Bacteria in mosquito cells can block transmission of Zika virus.
