I have close to 3 decades of experience in environmental radioactivity and environmental chemistry, with a focus on emergency preparedness and risk assessment. My work spans source term characterisation, as well as the transport, transfer, and impacts of radionuclides in the environment. I am particularly interested in how physico–chemical properties and multiple stressors influence their behaviour and this is studied via field studies, laboratory experiments, advanced analytical techniques, and modelling to support robust impact and risk assessments. This perspective also extends to other environmental pollutants, including metals and micro- and nanoplastics.
I currently lead the Environmental Radioactivity research group at the Norwegian University of Life Sciences (NMBU). I also chair Research Theme 5, Environmental Radiochemistry and Source Characterisation, at the Norwegian Nuclear Research Center (NNRC), and serve as scientific manager of the FIGARO gamma-UV irradiation facility at NMBU. From 2018 untill the end of the project in 2023, I was Research Director of the Centre for Environmental Radioactivity (CERAD CoE).
