My research team investigates the composition and function of the soil microbiome in agronomic systems, and how this knowledge can be used to inform agricultural management strategies.  We’re using new technologies to identify the microbes and pathways that underpin functions related to productivity, nutrient cycling and carbon sequestration. In addition, we’re investigating the effect of management, environmental and edaphic factors on the soil microbiome. We investigate the microbial communities responsible for the production of N20 (denitrifiers, nitrifiers) in soils and manures, with the aim of identifying regulators of each pathway and potential mitigation options. A key research focus of our group is on Plant-Soil-Microbial interactions and how they impact on soil fertility. We also study the prevalence, fate and transport of microbial enteropathogens and their indicators in the environment within soil, water, plants and organic amendments.

Research areas of interest for MSCA IF application:

  • Linking microbially mediated soil organic matter turnover to nutrient availability in agricultural soils
  • The effect of management, environmental and edaphic factors on the soil microbiome
  • Microbial communities responsible for the production of N20 (denitrifiers, nitrifiers) in soils
  • Impact of Plant-Soil-Microbial interactions on soil fertility
  • Adaptation of E. coli to the soil environment

Dr Brennan has supervised 3 PhD and 1 MSc students to completion. Currently her research team consists of 8 PhD students.
