Karen Johnson is a Professor in Environmental Engineering at Durham University. Having trained as a hydrogeologist, graduating with an MSc from University College London in 1995, she worked in the water industry (General Utilities/consultancy) for 3 years. She returned to academia in 1998 and completed her PhD in mine water treatment with Professor Paul Younger in 2001 at Newcastle University (NU). She worked at Newcastle University as a Research Associate until coming to Durham University (DU) in 2005.
Karen’s research has a strong emphasis on using ‘wastes’ as resources. To date, much of her research has focussed on the passive treatment of contaminated waters and soils using clean ‘wastes’ which were previously destined for landfill. Karen has a track record of multi-disciplinary projects collaborating both with industry, regulatory authorities, policy-makers, science and social science departments.
In 2016, Prof Johnson gave oral evidence to the Government's Environmental Audit Committee's Inquiry into Soil Health. She stated that urban soils are currently unprotected and that engineers should lead the way in the sustainable management of urban soils since soils have an important role to play both in climate change adaptation and climate change mitigation http://www.parliamentlive.tv/Event/Index/f77d63b0-bc6e-425b-aa47-ba63be60be99 …pic.twitter.com/wNU6gaXp5Y
Her more recent work has focussed on breaking the link between land insecurity and poverty in Africa (Sudan, Zimbabwe, Ghana and South Africa)
She is also passionate about raising public awareness of the importance of soil having worked with Pixelhouse Media to produce animations championing soil eg raising awareness of the link between soil degradation and flooding in conjunction with Hotspur Primary School and also about community regeneration of brownfield land ('A nation that destroys its soil destroys itself')
As PI, she has held or is currently holding funding for a number of recent projects:

Karen has developed fruitful collaborations with overseas academics (all Visiting Academics on current/past grants), for example in Zimbabwe - where she has established links with Professors Florence MtambaNgenwe and Paul Mapfumo at University of Zimbabwe, in South Africa with Dr Clarke at the University of Stellenbosch and in the US with Prof Tebo at Oregon University of Health and Science. She has also been a member of the EPSRC College from 2006.
Currently, Karen teaches “Polluted Environments and Sustainability” and “Materials” to third year MEng, MSc and BEng Engineering students. Student projects in are frequently linked with industry including Tarmac http://www.tarmac.co.uk NWL http://www.nwl.co.uk/ and Terrainfirma Ltd http://www.terrainfirma.co.uk.
Professor Johnson is also the Director of Research for her department and is keen to raise the profile of women in engineering (https://www.youtube.com/watch?v=1Q40dD0pzUk)
