Background and activities
My research interests lie in understanding soil-plant-herbivore interactions. My work takes an experimental field-based approach to studying both aboveground and belowground processes that influence carbon and nutrient cycling. In particular, my research focuses on the impact on the impact of grazing management (livestock and wild grazing) on key ecosystem components. As livestock grazing is a mainstay of rural livelihoods, a lot of my research involves interacting with farmers, landowners and other stakeholders. I have conducted research in temperate, oceanic and tropical biomes and on grazed islands, plains and uplands. Currently I am involved in the AfricanBioServices project with the overall aim of unraveling how human land-use and climate change impact key ecosystem functions, namely plant productivity and nutrient cycling.
