About

On Twitter, Facebook, and Instagram I'm taking walking people through some of the biochemistry work I do, as well as fundamental biochemistry concepts using and I'll be re-posting some of the posts here. (You can find links to all of my past posts here: http://bit.ly/2OllAB0). Feel free to ask questions and call me out if I slip into jargon!
