معرفی
Teemu Hölttä is a Professor in the Department of Forest Sciences at the University of Helsinki's Faculty of Agriculture and Forestry. He holds a docentship in the same department and is affiliated with the Viikki Plant Science Centre (ViPS) and the Ecosystem processes research group within INAR. Hölttä serves as a supervisor in the Doctoral Programme in Atmospheric Sciences and the Doctoral Programme in Plant Sciences.
His research focuses on the Physiology of xylem and phloem transport of water and sugars, xylem cavitation and cavitation reversal, the linkage of xylem and phloem structure and function at the whole tree level, tree's water and carbon exchange with the atmosphere and soil, cambial growth, soil water relations, and the response of stomatal conductance, photosynthesis and growth to drought and freezing. He has developed models to interpret various ecophysiological measurements including Stem diameter change measurements, Stem CO2 efflux measurements, and heat based xylem sap flow measurements.
Hölttä's publication record spans from 2002 to present with 163 publications. His recent research (2023-2025) shows strong focus on tree hydraulics, carbon dynamics, and responses to environmental stressors, with publications in high-impact journals like Plant Cell and Environment, Tree Physiology, and Journal of Hydrology. His work demonstrates interdisciplinary integration of forest ecology, plant physiology, and biophysical modeling.
He leads and participates in multiple significant research projects including TreeBio (Centre of Excellence in Tree Biology), The Hidden Role of Gases in Trees, and FORGENIUS. Hölttä is actively involved in the scientific community through conference presentations, workshops, and collaborative research activities.
As a Principal Investigator for the Viikki Plant Science Centre and project leader for TreeBio, Hölttä plays a key role in shaping forest science research at the University of Helsinki. His work bridges fundamental plant physiological processes with practical forest management concerns, particularly regarding tree responses to climate change and environmental stressors.
