PhD fra Institutt for Geofag, UiO 2012. Jobbet på CICERO siden 2005.


  • AC/BC På leting etter svevende sot, og hvordan det påvirker klimaet
  • Bio4Clim Comparative climate impact assessment of the forest based bio-economies of Norway, Sweden and Finland
  • MOCA: Methane Emissions from the Arctic OCean to the Atmosphere The MOCA project will enhance understanding of the present atmospheric effects of methane released from dissociation of gas hydrates in Arctic seabed sediments, and will also inform on the future potential impacts in a warming climate on decadal to centennial timescales.
  • Impact of absorbing Aerosols on Radiative forcing in the European Arctic The climate impact of absorbing aerosols, such as black carbon particles originating from fossil fuel combustion or biomass burning, mineral dust and volcanic ash, is still very poorly understood especially its role in the atmosphere of polar regions.
  • ICOS-Norge Integrated Carbon Observation System (ICOS)-Norway
  • Health effects of Hebei PM2.5 Action Plan As part of the preparation of a World Bank Program-for Results (PforR) operation on PM2.5 pollution in Hebei, the current report provides an economic evaluation of the health benefits that may be achieved from alternative scenarios for PM2.5 reductions in Hebei in 2017 and onwards. We also include a qualitative evaluation of other benefits, e.g., how the program may contribute to abating emissions of CO2 and short-lived climate forcers (SLCF).
  • Key Earth System Processes to understand Arctic Climate Warming (KeyClim) The objective of the KeyCLIM project is to develop The Norwegian Earth System Model (NorESM) to assess performance, develop and evaluate physical processes in the modell. A special effort is addressed to the near and long term future climate for the Artic, northern latitudes and Norway. Open data from the project will be provided to the climate mitigation and climate impact community.
  • CICERO skal forske på klimaeffektene av hydrogenutslipp Selv om hydrogen ofte omtales som en grønn energibærer som har potensiale til å erstatte olje i fremtiden, er klima- og miljøeffektene av hydrogen lite kjent. Dette skal CICERO gjøre noe med i et nytt forskningsprosjekt.
