Marianne Pascale Bartels is a senior research associate at the Institute for Advanced Sustainability Studies. Marianne joined the 'Role and Potential of Unconventional Gas' group in 2013 and her work encompassed all aspects of the shale gas debate but specifically stakeholder dialogue and public engagement across Europe as well as greenhouse gas and air pollutant emissions associated with a possible shale gas development in Europe. Marianne is now part of the Arctic Governance research team and her research focuses largely on oil and gas resources in Arctic regions and questions of resource estimates, scientific knowledge production, use and communication. Prior to joining the IASS, she worked in the oil and gas industry for five years on projects including conventional oil and gas, shale gas and coal bed methane exploration as well as geothermal drilling projects worldwide. Her experiences of the human implications of hydrocarbon exploration around the world led her to her research at the IASS. Marianne lives in Potsdam with her husband and two children and is a keen marathon runner.
