I study the interactions between soil, vegetation, and the atmosphere, focusing on the nitrogen and carbon cycles and greenhouse gas emissions. My primary research area is the climate impact of agriculture, including emissions, sinks, and processes influencing the fluxes of GHGs. I lead the SMEAR-Agri research station at the Viikki Research Farm, coordinate multiple research projects, participate in international collaborations, and supervise numerous postdoctoral and doctoral researchers. Additionally, I am involved in studying the carbon cycle of boreal and tropical forests, particularly regarding methane (CH₄) and nitrous oxide (N₂O) emissions and sinks from trees.
