Synthetic Biology deals with the engineering of biological processes to perform specific tasks. What makes engineering in biology different from engineering in the inanimate world is what’s increasingly referred to as ‘complexity’. Complexity means many things, but for us it will mean that biological organisms are characterized by hierarchies of self-assembled networks. These are networks of interacting molecules at the level of the cell, interacting molecules and cells at the level of tissues, interacting organs at the level of the organisms and finally interacting organisms at the level of eco-systems. These interactions are enormous in number, are organized in space and time and are typically non-linear, making the task of understanding them in full generality currently impossible. However what we can do is to understand fundamental properties of simpler interacting non-linear systems, and use that to help us figure out specific questions about cellular, organismal or eco-system responses. For example, bacterial and mammalian cells undergo chemotaxis. But chemotaxis involves some rudimentary information processing, and a cellular “decision”. How do biological networks process information and how does that information processing lead to a cellular decision is the kind of question that we ask.

In the first part of the course, we will look at small systems and try to understand the consequences of nonlinearity. What we’ll find is that nonlinear biochemical networks display fascinating and non-trivial behavior that has important biological consequences. We will explore some of these consequences, at different scales. We will also look at some exciting engineering applications in the field of synthetic biology.

In the second part of the course, we will ask how we can use biological data to determine the structure and properties of biological networks. We will explore the dynamics of genetic transcription and translation, emphasizing inference of the network of interacting genetic factors believed to be responsible for controlling timing of a wide-array of biological processes (such as cellular cycles and circadian rhythms) in a variety of organisms. We introduce tools designed to use time-course gene expression data to aid in the discovery of both the key participants in the network and the functional relationships between them.

The course organizers are Ashok Prasad[1], Patrick Shipman[2], and Lev Tsimring[3]. We are really excited to be organizing this school. Please address all questions to an organizer.
