Overview

Synthetic biology concerns the design and construction of new genetic parts, bio-molecular devices, and synthetic organisms. The topic is highly interdisciplinary, involving molecular biology, genetic engineering, protein design, metabolic engineering, computer engineering and mathematical modeling. Synthetic biology emphasizes the use of rigorous, quantitative engineering methods. Approaches and results in synthetic biology are rapidly being translated to industry and its applications are wide ranging.

Course structure

Classes will involve a mixture of paper discussions, lecture presentations by the instructors and in-class working sessions.

Pre-requisites

EE/BIOEN 423/523, CSE 486; or EE/BIOEN 425, CSE 488; or permission of the instructors. Students who are taking Advanced Synthetic Biology are expected to have a working knowledge of gene regulation and of the tools used to model genetic or metabolic circuits (e.g. differential equations, chemical reaction networks, stochastic chemical equations and similar). Familiarity with Matlab, Python or similar is required.

Approach

Synthetic biology covers an enormous wealth of different sub-fields and approaches. There is no established syllabus for synthetic biology and there is no single technical skill that is absolutely necessary to be successful. Still, there is one essential meta-skill that you need to acquire and that is the ability to identify an interesting problem that you have a chance to tackle with the tools you have. Moreover, once you think you have identified a potentially interesting problem, you need to be able to tell others (your peers, funding agencies, ...) about it and convince them that your problem is interesting, solvable and original. The goal of this class is to develop such skills through a set of examples.

The examples will come from four resarch directions that I personally find interesting:

Within each topic, I will present some of the background and (mathematical) methods that could be used to tackle the problem. Then, we will flesh out a project together and see whether we can come up with a coherent story that could be the foundation for a research grant.

Grading

You will prepare a written report for three of the four topic areas. Two of these reports take the form of a 2-3 page white paper or pre-proposal. For your favorite topic you will write a longer (up to 6 page) research grant. Reports will typically include a succinct problem statement including specific aims, preliminary data in the form of a model and a background section with citations. Each of the two shorter white papers accounts for 25% of your grade, the full proposal accounts for 50%.
