In my group we are interested in computational synthetic biology. We are developing the Synthetic Biology Software Suite, a publicly available software suite that assists in rationally designing synthetic gene regulatory networks. We combine components from BioBricks to generate networks of biomolecular reactions. We combine stochastic-discrete, stochastic-continuous and continuous-deterministic models to simulate these reaction networks. Version 1.0.2 is available on Sourceforge.net [1]. We are now incorporating the connection with BioBricks.

In recent work (Ramalingam, KI, Tomshine, JR, Maynard, JA, Kaznessis YN. " Forward engineering of synthetic bio-logical AND gates" Biochemical Engineering Journal, 2009, 47(1-3):38-47), we used multiscale models of gene regulatory networks to design, build and test bio-logical AND gates.

We are also participating in the iGEM competition. We were awarded a Gold Medal in 2009 for SynBioSS work.
