Developing Standardized Cell-Free Platforms for Rapid Prototyping of Synthetic Biology Circuits and Pathways
The goal of this project is to further advance standardized cell-free systems from engineered E. coli and other organisms for use in prototyping synthetic circuit and pathway designs. Such standardized systems will both explore the boundaries of cell-free prototyping and characterization, and enable more detailed understanding of key mechanisms, accelerating the usage and broader utility of cell-free systems in industry and academia. The long term vision for this project is to establish cell-free systems as a platform for implementation of synthetic biological circuits, pathways, and systems, where modular and complex biomolecular systems can be engineered in a systematic fashion. This project seeks to overcome some of the current limitations of cell-free systems through a combination of experimental characterization and computational modeling.
