My research interests are in plant community ecology, especially in tundra, and I’m studying how environmental changes and biotic interactions impact ecosystem functioning via plant communities.
My postdoc project explores how environmental changes and biodiversity impact ecosystem multifunctionality. Environmental changes can affect ecosystem functions in two ways; directly, and indirectly by affecting biodiversity. In this project I compare the strengths of direct and biodiversity-mediated effects of environmental changes on several simultaneous ecosystem functions, so called multifunctionality of ecosystems. I use diversity of functional traits as a measure of biodiversity and investigate how climate warming, herbivory and soil nutrients influence multiple ecosystem functions. As methods I use long-term field experiments in Finland and Greenland to study this in real ecosystems and mesocosm experiments in Belgium to test mechanisms driving the observed patterns in nature.
Currently I am working as International Post-doctoral Researcher funded by Swedish Research Council via University of Umeå, supervised by Prof. Harry Olde Venterink at Vrije Universiteit Brussel and Prof. Eric Post at UC Davis.
Summary of previous research
2014-2015: Post-doctoral researcher at Nordic Centre of Excellence Tundra, University of Umeå
NCoE Tundra investigated the complex climate-animal-plant interaction of the tundra ecosystem and explored the capability of herbivorous mammals in controlling and inhibiting the expansion of woody vegetation. I was part of a working package called ‘Impact of vertebrate herbivory on tundra vegetation’ led by Dr. Johan Olofsson. My task was to analyze data and manage a long-term field experiment studying the effects of warming and herbivory on tundra plant community.
2008-2014: PhD studies at University of Umeå, supervised by Johan Olofsson, Jon Moen (Umeå) and Anu Eskelinen (University of Oulu, Finland)
In my PhD thesis I showed how herbivores can prevent expansions of plant individuals to open tundra and revert warming-induced changes in local plant communities. As methods I used field several experiments manipulating temperature and herbivory in different parts of Fennoscandian tundra.
