Dr Michelle Cain
Lecturer in Environmental Analytics
University of CranfieldMichelle’s core expertise is in greenhouse gases, air pollution and climate science. Her current research focuses on the role of greenhouse gases other than carbon dioxide in limiting global warming, consistent with the Paris Agreement’s temperature goal. In particular, how to estimate the temperature outcomes from reducing methane emissions. Agricultural emissions are dominated by methane and nitrous oxide, both potent greenhouse gases. However methane’s lifetime in the atmosphere is around a decade, whereas nitrous oxide’s is over a century, and so methods of comparison must account for this to be accurate over all timescales.
Before joining Cranfield in 2020, Michelle was a senior researcher at the University of Oxford, where she developed the Oxford Martin Programme on Climate Pollutants, which aimed to make climate metrics used in climate policy more fit-for-purpose. She held two University of Oxford Knowledge Exchange Fellowships, on agricultural climate mitigation.
As a postdoctoral researcher at the University of Cambridge (2009-2017), Michelle worked on modelling the sources of pollution measured by the Cranfield-based FAAM research aircraft. She took part in conducting large field campaigns to the Arctic to measure methane in the atmosphere, linking these measurements back to sources such as remote wetlands. Other field campaigns targeted UK air pollution, and fugitive methane from North Sea gas rigs.
Her PhD, from the University of Reading, combined airborne measurements with modelling of long range transport of pollutants in the atmosphere from North America to Europe, and also in the West African Monsoon.

Professor Steve Banwart
Director, Global Food and Environment Institute
University of LeedsFor the first three years of the FixOurFood programme Steve brought expertise in soil research and theoretical mathematical modelling, but very sadly he passed away in December 2023.
Steve held the University of Leeds Leadership Chair in Integrated Soil – Agriculture – Water research and was Director of the Global Food and Environment Institute. He championed integrating research on soil and water resources into the study of Earth’s Critical Zone, the surface layer of the planet from bedrock to atmospheric boundary layer that provides most life-sustaining resources. He obtained a BSc in Civil Engineering and a MSc in Environmental Engineering from the University of Iowa and a PhD in Natural Environmental Science from the Swiss Federal Institute of Technology – Zurich. His core science was basic chemistry that is also applied to the study of soil systems and natural waters. His achievements include combining laboratory experimentation, theoretical mathematical modelling, and data from field studies in order to describe water flow and transport and mechanism of chemical transformations that quantify: (a) Soil functions that produce crops, store and filter infiltrating water, transform nutrients, store carbon from the atmosphere as organic matter, provide habitat and sustain biodiversity, (b) Weathering of rock and minerals to deliver solutes to drainage waters in catchments and river basins including the release of contamination from mining sites and (c) Role of the geological barrier to contain civilian high level nuclear waste within underground repositories constructed in bedrock Biogeochemistry and natural biodegradation of hydrocarbon pollution in soil and groundwater aquifers.
