Overview

Our research integrates biochemistry, genetics and mathematical modelling to characterise fundamental mechanisms of gene control and to understand how these elements are combined to create gene regulatory circuits with complex functions. Having a detailed understanding of the properties of natural regulatory circuits makes it possible to rearrange these components to build our own circuits with new and interesting behaviours. In this way, we have developed a number of useful tools for Synthetic Biology.

Our primary experimental systems are two E. coli bacteriophages, lambda and 186. These temperate phages can replicate their genomes using alternative developmental pathways, lysis and lysogeny, and are some of the simplest organisms to make developmental decisions. Despite their relative simplicity, the phage systems combine a wide range of gene control mechanisms in complex ways and have many lessons to teach us. Bacteriophage lambda continues to be a key model system for many molecular biological processes; phage 186 provides a powerful comparison with lambda, as it achieves similar outcomes using different regulatory circuits. The fundamental biochemistry shared by all living things means that the study of any organism, from phages to humans, continues to illuminate universal principles that apply to all organisms.

We also have a strong interest in isolating and characterising new phage for phage therapy - phage are natural killers of bacteria and there is renewed interest in their use as anti-bacterial agents.
