This is a joint project with John Doyle, funded by the ARO Institute for Collaborative Biotechnology. This page primarily describes the work done in Richard Murray's group.

Current participants:

  • Dionysios Barmpoutis (PhD student, CNS)
  • Elisa Franco (PhD student, CDS)
  • Ben Prindle
  • Ophelia Venturelli (PhD student, BMB)

Previous participants:


We are developing a theoretical foundation for a network science relevant to the understanding and design of complex "systems of systems" typified by biological networks. We are particularly focusing on the organizational principles underlying their ``robust yet fragile aspects, scalability, and evolvability, and demonstrating progress with case studies of varying detail using familiar and concrete examples from biological networks and network-centric technologies. Biological examples will focus on intracellular regulatory networks and intercellular communication.
