Biomaterials Evolution
This platform will create massively-parallel capabilities for directed evolution of biomolecules, such as DNA,
for regenerative medicine and bioenergy Wyss Faculty Lead: George Church
Other Wyss Faculty: Pam Silver William Shih Jim Collins Don Ingber
Overall Goals: • Directed Evolution of Human Antibodies • Multi-Gene Switches for Cell Reprogramming• DNA as a Cost Effective Biomaterial
