 It's been an incredible 12 years. We've come from the very basic science, trying to discover genes in a metabolic pathway in a plant that makes a natural product, to getting those in a microbe and developing a process to produce in large scale this drug that people need. And it's a really simple process, right? It's like brewing beer. Well, these are engineered microbes that are producing biofuels. They are growing in a broth. This started in my laboratory right around 2000. We were trying to figure out what we work on. One day, one of my graduate students said, Jay, look at this molecule. It's an anti-malarial drug. It means life and death for a lot of children whose parents can't afford the drugs. And we looked at that and thought, gosh, this ought to be something we can produce.
