Nygårdsgaten 112, 5008 Bergen, Norway

Dr. Nicole Dopffel (born Klüglein) studied biology in the University of Tübingen, Germany, and obtained her PhD in geomicrobiology on the topic of anaerobic, microbial iron-cycling in 2014 (Bacterial Fe(III) reduction and Fe(II) oxidation – relevance for magnetite formation in the environment and the mechanism of nitrate-dependent Fe(II) oxidation). From 2014 until 2019 she worked as lab leader and researcher in the chemical company BASF (Ludwigshafen, Germany) where she focused on oilfield- and industrial-related microbial problems including microbial enhanced oil recovery (MEOR), microbial souring, microbial corrosion, biopolymers and growth control. Since 2019 she works as a senior researcher in the Norwegian research institute NORCE in Bergen, Norway. Her focus are cross-disciplinary research projects on sustainable energy topics including:

- Microbial processes and risks during hydrogen underground storage

- Microbial plugging in geothermal installations

- Biohydrogen production from waste

- Biohydrogen production within reservoirs

- Biodegradation processes

- Microbial processes in soil, water and the subsurface

- Microbial influenced corrosion
