Welcome to Cognitive Feedback Loop. This blog was started with the intended purpose of bridging the gap of communication between scientists and the general public. I write about things from the world of science that are interesting and important. I also produce the included illustrations to help simplify the message, because a picture is sometimes worth 1000 points of data. And in the spirit of academia, I also include copious hyperlinked references to the original research articles.

I studied chemistry in college, and biochemistry for my Ph.D. Now I work as a researcher in a virology lab at Arizona State University. You can see my bibliography below, or a full portfolio here.

If you are interested in working with me on a writing piece or an illustration please contact me at robert@cognitivefeedbackloop.com, and maybe I can help you out. In most cases I would charge no fee and only ask that you mention my name in your acknowledgements.

Thanks for visiting my blog. I hope that you find an article that you enjoy reading, and a diagram that resonates with your imagination and gives you some cognitive feedback!
