Synthetic Biology

OVERVIEW

Synthetic biology is the process of designing and engineering organisms with new traits and behaviors. In the Wiles Lab we are using synthetic biology to dissect the inner workings of host–microbe systems. We use fluorescent proteins to track bacterial activity and evolution within complex environments such as the vertebrate intestine. We also control bacterial behaviors with genetic switches to probe the mechanisms underlying host–microbe interactions. Ultimately, synthetic biology enables us to expose previously unrecognized aspects of host–microbe systems, opening new avenues for therapeutically manipulating the microbiome.

Below is a genetic switch we built to control bacterial swimming behavior. Once triggered with the inducer molecule aTc, bacteria go from swimming and expressing the fluorescent protein dTomato to not swimming and expressing green fluorescent protein.
