SLCU's newest Group Leader introduces himself

last modified Dec 07, 2017 02:09 PM

I have always held a deep fascination with the natural world and this was almost certainly fuelled by my early years living in Zambia and seeing first-hand the amazing African wildlife. My first experiences working with plants came when I joined the group of Brian Staskawicz at the University of California, Berkeley, to do a year-long undergraduate research placement.  It was an incredibly exciting time to be in Brian’s lab, I joined a project in which we cloned one of the first resistance genes, at a time when very few genes had ever been cloned from plants.  I was hooked, on plants, on genetics and on plant-microbe interactions. After my PhD, also with Brian, I wished to stay in plant-microbe interactions, but I wanted to change fields. I joined the group of Sharon Long at Stanford University and benefited immensely from the many years of hard work that had gone into making Medicago a model system in which we could dissect the processes that supported nitrogen-fixing symbioses.

I spent 15 years working at the John Innes Centre, attempting to understand how plants perceive symbiotic microorganisms present in the rhizosphere. Having contributed to a detailed understanding of symbiosis signalling, I now want to understand how this signalling process activates the developmental changes in the root leading to the formation of a nodule and intracellular bacterial infection.  In part, this shift in my research programme is driven by a fascination of how plant development is regulated by plant-microbe signalling, but it is also driven by the realisation that these developmental processes, rather than signalling, is what differentiates plants such as legumes that can associate with nitrogen-fixing bacteria from those plants, such as cereals, that cannot.

My research has always focused on developing a detailed understanding of symbiotic associations and is driven by a fascination of how these processes work.  However, in the last 5 years I have teamed up with the Bill and Melinda Gates Foundation on a programme of research to engineer nitrogen-fixing cereals.  There remains much to be discovered before we are likely to be able to transfer nitrogen fixation to cereals. However, I am very excited by the prospect that some day this research could address one of the greatest limitations to agricultural productivity and I am particularly motivated by the fact that the beneficiaries of my work could be some of the poorest people on the planet. I hope that the advances in our knowledge that we develop at SLCU could provide the foundations for creating more sustainable and equitable food production globally.
