Professor Jennifer Dungait is a Principal Research Scientist based at Rothamsted Research North Wyke where she leads the Soil Carbon Dynamics group, and she is a lead scientist on the BBSRC-funded North Wyke Farm Platform National Capability, and a member of the cross-institute Research Strategy Committee. Jennifer joined Rothamsted Research as a Senior Research Scientist in 2008, and spent 6 months as a Visiting Scholar at the Ohio State University, USA in 2012. She was previously a Research Associate in the School of Chemistry at the University of Bristol for 3 years.

Jennifer’s expertise is in biogeochemistry and soil science. She gained her first degree in Environmental Science at the University of London, followed by her MSc in Crop Protection at the Institute of Arable Crop Research at Long Ashton awarded by the University of Bath. Jennifer read for her PhD in Organic Geochemistry at the University of Bristol, which investigated the fate of cattle dung carbon in grassland soils using compound-specific stable isotope ratio mass spectrometry.

Jennifer’s research focuses on optimising soil carbon dynamics in agricultural soils and particularly livestock systems to support the development of environmentally-benign farming systems in a changing climate. Current major research themes inlcude (1) Abiotic and biotic controls on soil organic matter dynamics; (2) Reducing the carbon footprint of ruminant livestock production; (3) Is soil erosion a source or sink of carbon?

Jennifer has active international research programs with CIAT in Kenya and Tanzania and Colombia, the University of Western Australia, the Chinese Agricultural University and the Chinese Academy of Sciences, and the Indian Council of Agricultural Research. She provides expertise to the World University Network/Global Innovations Initiative ‘Global Farm Platforms for Sustainable Ruminant Livestock Production’, the Global Research Alliance on Agricultural Greenhouse Gases, and the China-UK Sustainable Agriculture Innovation Network (SAIN) ‘Low Carbon Farming’ project with the Chinese Academy of Science on soil organic matter management. She works with farmers and stakeholders in the UK developing strategies for increasing carbon stocks in soil to improve soil health and quality in agricultural systems and has received funding from the Westcountry Rivers Trust and AHDB Beef and Lamb.

Jennifer is a Visiting Professor of Sustainable Agriculture at the Royal Agricultural University. She is an Honorary Associate Professor at the University of Exeter in the College of Life and Environmental Sciences, where she has active collaborations in Biosciences and Geography and coordinates the Sustainable Land-use in Grassland Agriculture module of the MSc in Food Security and Sustainable Agriculture, and lectures on Soil Organic Matter. She maintains strong links with the University of Bristol through joint studentships and the Food Security Land Research Alliance and the Global Farm Platoform. She is an invited lecturer at the University of Gothenburg, Sweden where she contributes to the 'Biogeochemistry and the Rhizosphere' PhD course. She is an Associate Editor for two international soil science journals. She is Chair of the 6th International Symposium on Soil Organic Matter which will be held at Rothamsted Research from 3-8th September 2017.
