The Centre of Excellence in Tree Biology (TreeBio) integrates ten Principal Investigators (PIs) from the University of Helsinki and two from Natural Resources Institute Finland (Luke). Researchers from the Faculty of Biological and Environmental Sciences and Faculty of Agriculture and Forestry at the University of Helsinki are part of the consortium.

Ari Pekka Mähönen

I am an expert in meristem biology. My group will focus on understanding carbon sequestration by wood forming cambium and will identify key factors regulating cambium activity. With the help of modelling, my aim is to understand how wood formation controls sink strength, and how sink strength changes feed back to the function of stomata and conductive tissues.

I am the CoE PI and Coordinator of WP3: Carbon sink: Developmental regulation of carbon sequestration in wood.

Teemu Hölttä

I am an expert of whole plant ecophysiology related to plant water and carbon relations. In TreeBio I will play a major role in integrating the three experimental research lines by modeling and whole plant approaches.

As a senior scientist I am the leader of Task 6 (WP2) and 9 (WP3).

Kaisa Nieminen

My research at the Natural Resources Institute Finland (Luke) addresses the genetic regulation of wood formation and plant growth in silver birch, poplar and alder trees. My work is highly integrated into Lukeʼs ongoing tree breeding programs.

As a senior scientist I am the leader of Task 13 (WP4).

Tanja Pyhäjärvi

I am an expert on the analysis of natural variation in trees and I will be responsible for the population genetic and association mapping analyses.

As a senior scientist I am the leader of Task 11 (WP4).

Jarkko Salojärvi

I am an expert in computational analysis of biological data and I will be responsible for the genomics and bioinformatics aspect in TreeBio.

As a senior scientist I am the leader of Task 12 (WP4).

Alexey Shapiguzov

I am studying molecular mechanisms that link photosynthesis and respiration to plant stress response and to guard cell functions. I also work at the Natural Resources Institute Finland (Luke) where we develop new approaches in phenotyping plant performance and stress.

As a senior scientist I am the leader of Task 10 (WP4).

Melis Kucukoglu Topcu

I am a plant developmental and molecular biologist with a strong expertise in genetic transformation of trees. My research line is at the interface of plant growth and development, translational biology and molecular breeding, with special interest in the molecular control of cambial meristem activity and wood formation in trees. 

As a young PI I am the leader of Task 8 (WP3).

Maija Sierla

I am a plant molecular and cell biologist with an interest in how plants sense and respond to changing environmental conditions. My group studies guard cell signalling, stomatal function, and the connection of stomatal function and vascular water transport.

As a young PI within this CoE I will investigate stomatal regulation and functionality of conductive tissues and I am the leader of Task 5 (WP2).

Anne Vatén

I am an expert of stomatal development. My group will dissect molecular mechanisms, which control stomata formation during leaf development upon environmental fluctuations, and thus modulate resource allocation, CO2 uptake and water loss.

As a young PI I am the leader of Task 2 (WP1).

Cezary Waszczak

I am a plant molecular biologist with a strong background in reactive oxygen species signaling, photorespiration, and stomatal biology. My current research interests revolve around the cell wall structure/composition and its impact on epidermal integrity.

As a young PI I am the leader of Task 1 (WP1).
