Stomatal control, tree water relations and photosynthesis modelling.
My PhD project focuses on the theory of stomatal control and gas exchange in trees. I've been developing a new theoretical framework for stomatal control functions and trying it out using the land surface model JSBACH. I'm also part of the micrometeorology group at INAR / Physics.
Xylem, nutrition, tree growth modelling
Focused on the height growth decline of old-growth trees, my research centralizes on the hydraulic dynamics and nutrition conditions of the predominant tree species of Finland. Both field measurements and laboratory means are employed in my studies, yet in mathematics I the most trust.
Tree ecophysiology, hydraulic conductance, root systems, drought stress
I am now focusing on the hydraulic conductance of the Scots pine root system, especially effects of the root length on hydraulic properties. In addition, i will cover the implication of hydraulic conductance of the root systems for the distribution of soil water and modeling draught.
My research project focuses on the biogeochemical and biophysical feedbacks from forest harvesting. More specifically I study the impact of forest management in tree physiology and the tree-soil interactions in different soil conditions.
Leaf stress relations to optical properties
In my PhD thesis, I focus on improving ways of measuring plant physiological processes through optical means. More specifically the aim is to create a new low-cost sensor for fluorescence imaging and to link the leaf level measurements to canopy level measurements done with drones.
Tree root growth, morphology and rhizosphere microbiology
My main topic is to study how forest managements and climate changes affect tree root growth, morphology and rhizosphere microbiology. In addition, I will study the interaction between root and rhizosphere microorganisms.
Tree root carbon dynamics in boreal forests
My research interests are tree root carbon dynamics in boreal forest ecosystems. The aim of my research is to quantify and model carbon-related processes of Scots pine roots in the framework of whole tree carbon balance and estimate tree carbon dynamics in the chancing climate.
Tree ecophysiology, xylem and phloem anatomy, tree hydraulics
I want to know, how trees can acclimate to drought and to gain new insight into tree hydraulic architecture. Therefore, I study xylem traits, especially pits, as well as phloem traits in trees grown on sites with different water availability. Also, I want to understand better how structure and function are coupled and will combine hydraulic and anatomical measurements.
Forest modelling under climate change, remote sensing
My thesis is working on the process-based modelling on forest under climate change, and also try to combine with remote sensing data to develop on a larger area.
Forest tree ecophysiology, nutrient balance
My main topic is to study carbohydrate relation with photosynthesis and water transport in boreal woody plants. I am also developing different laboratory protocols, mainly biochemical analyses woody plant material.
Leaf optical properties
During my PhD and as a member of FLUO-SYNTHESIS project, I study the variation in leaf optical properties (absorption, fluorescence and reflectance spectra) across species, light gradients and in response to multiple sources of stress.
Sources of methane emissions from trees in boreal forests
Working for the project From Processes to Modelling of Methane Emissions from Trees (MEMETRE).
My PhD project focuses on energy partitioning in and between photosystems I and II during light reactions. To understand the variability spatial (e.g. species, environmental conditions) factors cause to these mechanisms in daily and seasonal scale, I will perform optical and gas-exchange measurements both in field and laboratory conditions.

Drought impacts on plant phloem physiology
I am working as a doctoral student on the physiology of phloem transport. Particularly, I want to study how stress impact carbon and water fluxes inside plant individuals. Previously I worked on provenance/inheritance based plant trait variation and plant invasion physiology. I am generally interested in plant sciences, ecology, biogeography and paleontology.
