My research involves:
1. Growth trends and climate relationships
2. Potential yield capacity estimation from the site index of planted forest tree species.
3. Leaf area index modelling in a heterogeneous forest ecosystem.
4. Long-term effects of future climate conditions and management on forest growth.
I am involved in SLU's environmental monitoring and assessment programmes related to carbon and biomass dynamics, as well as forest growth.
I have a background in forest resource management from Ghana during my bachelor studies and from Europe during my studies in the Sustainable Forest and Nature Management programme.
I am involved currently in an MSc thesis on the estimation of the time for first thinning in Scots pine stands using repeated airborne laser scanning data.
