BVOC's, VOC emissions, biosphere-atmosphere interactions
My main research topic is how biosphere influences the chemical composition of the atmosphere, in particular the biosynthesis and emissions of biogenic volatile organic compounds (BVOC's) from both terrestrial and aquatic ecosystems. These processes significantly influence the atmospheric aerosol formation in the boreal forested areas, and are thus contributing to climate change.

Forest production ecology, forest growth, wood quality, process-based growth modeling
My research field is production ecology, and my special interests are in understanding how trees capture resources and how they allocate them to form a spectrum of structures that appear so well adapted to the prevailing environment. I lead the Forest Modelling Research Group which develops theories and models of tree function, structure, and growth, and applies these to questions relevant to forest management under changing environmental conditions and alternative management objectives.
Greenhouse gases in boreal forest soil and trees, methane, nitrous oxide
Greenhouse gas sources and sinks in boreal forest soils and trees, processes of methane and nitrous oxide exchange and factors affecting the fluxes. Seasonality in the production, transport and emissions of CH4 from trees in boreal forest ecosystems, revealing sources of biological methane production in boreal upland forests.
Xylem transport, phloem transport, tree water relations
My research focuses on the water transport from the ground up to the leaves in the xylem and the transport of sugars from the leaves into other parts of the tree in the phloem. The transport processes and their functionality in varying seasons and environmental conditions create limitations for tree size and structure and also affect the carbon assimilation capacity of a tree.
