Objectives
We are working to develop a new class of feedback circuits that makes use of synthetic biological components to implement rapid response to input signals in a more robust and modular fashion. Our approach is to make use of biological processes that operate on timescales of seconds to minutes, primarily through feedback mechanisms using allosteric and covalent modifications that affect protein function. We are exploring the use of the modularity of protein domains to design circuit elements that can be reused more easily than existing components, and we will test our circuits across a variety of cellular contexts to assess robustness as a fundamental property of the design.
