Biography
Alexandra Pehlken studied Mining and Mineral processing at RWTH Aachen University in Aachen, Germany. She performed her doctorate degree at the Mining Faculty in 2002. Her expertise lies in the secondary resource management and the cascade using of materials with its impact on the life cycle performance. While being an expert in recycling, she is also involved in renewable energies. Succeeding her doctorate degree she was granted a scholarship from Germany to work for two years (2004-2005) at Materials Technology Laboratory (MTL) NRCan in Ottawa, Canada. From March 2014 until September 2019 she was head of the research group Cascade Use at Carl von Ossietzky University. Since June 2019 she is a member of the Energy division at OFFIS. Her current research focus lies on assessment of sustainable resource management in relation to the assessment of materials needed for renewable energies and sustainable transportation. She is a lecturer in Bioenergy for the international masters program “Postgraduate Programme Renewable Energy (PPRE)” at Oldenburg University. Since October 2015 she is also the head of the Steinbeis Transfercentre Resource. Since 2018 Alexandra is external evaluator for the EU Horizon 2020 research program.
