I work as a senior researcher at the School of Forest Sciences of the University of Eastern Finland. I obtained the degree of Master of Science in Agriculture and Forestry in 2008 and a PhD in 2016, both from the University of Helsinki. In addition, I also hold a Master of Arts in Education (2014) also from the University of Helsinki.
My research focuses on understanding dynamics of forests and trees through growth and competition as well as the effects of disturbances. I utilize a variety of remote sensing techniques such as laser scanning (both terrestrial and airborne) and satellites.
In addition to the Universities of Helsinki and Eastern Finland, I have worked as a Visiting Research Scientist at the Canadian Forest Service of the Natural Resources Canada as well as at the Ghent University (Belgium).
