Research
My current research work falls into two broad areas: (i) developing and applying experimental approaches to link the soil microbiome to measures of biogeochemical cycling in plant-soil systems, with the aim of understanding the interaction between plant inputs, microbiome and GHG emissions; (ii) using long term field trials, to identify factors in agricultural systems responsible for structuring of microbial communities and how this may affect plant productivity and GHG emissions. I am currently involved in a number of projects;
