ior. Computer scientists in synthetic biology teams help design the DNA fragments that must be inserted into a living cell and verify that the resulting genetic network is robust in the sense that small variations within the engineered cell mechanism are tolerated and will not result in malfunction.

The annual iGEM competition mentioned earlier is backed by a number of corporations, including Microsoft, which has established a systems biology group at its Research Center in Cambridge, England; researchers there explore the applications of Milner’s -calculus—developed to check the properties of mobile hardware, like cell phones—in systems biology. Ensuring that within a certain area a given number of calls can be handled properly by a provider’s technology has counterparts in systems biology. As such, a team led by Luca Cardelli, a Microsoft computer scientist in Cambridge, who previously engaged in research aimed at ensuring the correctness of distributed programs, is today developing formal languages to describe cell behavior [ 6].

Even if systems and synthetic biology experiments look simplistic, they are indeed the early prototypes of major advances in the field. With the help of

computer science, researchers and engineers will achieve the progress needed to transform systems and synthetic biology from pure science to indus-trial-scale reality. c
