I completed my master degree in Department of Environmental sciences of the University of Helsinki. I have worked on a study of possible effects of artificial aeration on greenhouse gas concentrations and fluxes in a boreal lake ecosystem. Since that, I realized how much fun there is in field works as well as laboratory analysis in research.

I started my PhD in the University of Eastern Finland in May 2016. In BGC research group, I am studying the emissions of reactive gases from boreal forest terrestrial ecosystems in the field. My study sites include non-permafrost and permafrost soils in Lapland and in Siberia, respectively. Forest and permafrost soils are potentially large sources of BVOCs and HONO, because of the large amount of decomposing litter and soil organic matter. BVOCs and HONO are closely associated with air chemistry and aerosol formation in the troposphere. Fire disturbances have long-term effects on the ecosystems and their biological processes affecting also the emissions of reactive gases from soils. The magnitude of reactive gas fluxes from boreal forests and the effects of disturbances on them are one of the biggest uncertainties in predicting the effect of climate change. Thus, I aim to determine the BVOCs and HONO fluxes from soil along with forest succession since the last fire.

Research interests

  • BVOC fluxes released from different biomes
  • Emissions of HONO and greenhouse gases along with forest succession
  • Climate change effects in Subarctic and Arctic regions
  • Biogeochemical processes affecting soil carbon and nitrogen cycling in terrestrial ecosystem
