Professor Karen Hudson-Edwards

University of Exeter

Karen Hudson-Edwards is Professor in Sustainable Mining at the Camborne School of Mines and the Environment and Sustainability Institute at the University of Exeter, UK. Her research focuses on understanding the character and geochemical mobility of mine wastes, and on designing management and remediation schemes to lessen their impacts on ecosystem and human health. Over the past 25 years she has worked all over the globe, studying the aftermath of tailings dam failures, the geochemistry, mineralogy and microbiology of different types of mine wastes and the effectiveness of remediation and management schemes.

Dr Laura Newsome

University of Exeter

I am a geomicrobiologist based at Camborne School of Mines, University of Exeter. I'm interested in understanding the behaviour of contaminants and metals in the environment, and how microorganisms can be used for bioremediation and bioprocessing applications. My research is interdisciplinary and incorporates microbiology, mineralogy and geochemistry to develop new insights into biogeochemical metal cycling in natural and engineered environments.

My research interests range from the nanoscale to the field scale. I use cutting edge microscopy and spectroscopy techniques to investigate the mechanisms by which microorganisms interact with metals and minerals. I work with samples that are naturally rich in metals and samples from metal-impacted environments, characterising their microbial communities and investigating how microbial processes can mobilise, redistribute and sequester metals. Iā€™m also interested in exploring how we can use microorganisms to help recover metals from ore deposits.

Professor Frances Wall

University of Exeter

Professor of Applied Mineralogy, Camborne School of Mines (CSM), University of Exeter. Frances will be concentrating on research to predict and mitigate environmental impacts of lithium production from different varieties of deposits by developing life cycle assessment and qualitative comparison techniques first applied to rare earth deposits in the SoS RARE project. Frances specialises in technology raw materials, with interests in geology, processing, responsible sourcing and circular economy. A former Head of CSM, Frances is PI for the new UKRI Interdisciplinary Circular Economy Centre in Technology Metals and has recently been leading two international consortium research projects on critical metals (, She also leads a large Deep Digital Cornwall project to encourage business RD&I, is part of the MIREU (mining and metallurgy regions of Europe Horizons 2020 project) project and a member of the Geological Society Decarbonisation Group. Frances was named one of the 100 Global Inspirational Women in Mining 2016 and awarded the William Smith medal of the Geological Society of London for applied and economic aspects of geology in 2019.
