Today’s ID the Future spotlights systems biology and the role engineers can play in some leading-edge biology. According to guest Steve Laufmann, systems biology is taking the biological world by storm, an approach that treats biological systems as optimally or near-optimally engineered systems and, using that working assumption, seeks to better understand the system. Laufmann says this provides an opening for engineers to contribute, since they have a deep understanding of what it takes to make a complex system work, and what’s required to change one core aspect of an engineered system so that it continues to work with all of the other crucial parts of the system. Many biologists aren’t trained in this, Laufmann says, and most engineers aren’t trained in the details of biology. Laufmann argues that the way forward is to get engineers and biologists talking, train biologists in engineering principles, and train engineers in biology. Laufmann and host Eric Anderson also discuss a recent conference they helped organize, the Conference on Engineering in Living Systems (CELS). Near the end of their conversation, Anderson asks Laufmann to tease some of the research work coming out of the conference, and Laufmann points to one researcher’s work on the bacterial flagellum, and promises more to come.
