Our lab is interested in how the bacterium Sinorhizobium meliloti establishes and maintains its nitrogen-fixing symbiosis with plants. Currently our research is focused on two areas:

•the cell biology of symbiotic infection

•signal transduction by the phosphotransferase (PTS) system and its role in regulating symbiotic, and other, functions

In addition we have been developing tools and techniques that let us use bacteria as biosensors in complex environments such as soil and the rhizosphere.

These are described in a bit more detail on the research page. Links to papers can be found on the publications page.
