  2018–2022
• BSc: Environmental Science
  2014–2017

Rob Brown is a Postdoctoral Researcher in Biogeochemistry working within the Ecosystems and Environment group. He is currently working on the BBSRC funded greenhouse gas removal demonstrator (GGR-D) project examining biochar as a tool for carbon sequestration. This interdisciplinary, multi-institution collaboration aims to address the uncertainties concerning the extent and scope of the deployment of biochar. The focus of his research is on the deployment of biochar to land, in particular the applicability of biochar as a carbon storage to tool in grassland soils; examining the effect of biochar application on soil and plant health, and ecosystem service delivery. Broadly, his research interests include; soil carbon dynamics, exploring biological function particularly through the use of novel methods (metabolomics and volatilomics), soil quality and radioisotope tracing.
