I am interested in how bacteria interact with plants. We use synthetic and systems biology approaches to better understand how molecular mechanisms impact on overall systems behaviour. Research activities span from molecular mechanisms that underpin bacterial system behaviour, to predictably alter their behaviour in plant environments. For example, we study the molecular program of Pseudomonas syringae that triggers plant pathogenicity and the regulation of nitrogen assimilation and fixation in a various bacteria. I am coordinating the systems and synthetic biology aspects of our strategic LoLa award to engineer nitrogen fixing bacteria to reduce our dependency on chemically produced nitrogen fertilisers (RCUK: BB/N003608/1).
