Paul Szejner, PhD

Research Scientist, Luke (Natural Resources Institute Finland) — coordinating the Finnish site of an ongoing Nordic forest-hydrology consortium project.

I am a forest ecologist. I use stable isotopes in tree rings to study the relationships between plant physiology and environmental changes. I am interested in the mechanisms driving carbon and water fluxes in forested regions from seasonal to centennial scales.

Research

My research builds upon advances in biogeochemistry, ecohydrology, dendroclimatology, and plant physiology. Using these disciplines, I combine time-series analysis with mechanistic modeling to interpret ecophysiological changes over time.

I use and collect data to condition models and organize general patterns that can explain Land–Ocean–Atmosphere interactions. Thus, I go back and forth between empiricism and theory, crossing scales ranging from cellular to global to understand tree–environment interactions. Throughout my research experience, I have developed the capacity to consolidate and establish large datasets that are useful to test hypotheses and bridge our understanding related to the effects of global changes from the plant to the continental scales.

I currently coordinate the Finnish site of a Nordic–Baltic consortium project on adaptive drainage in hemiboreal forests — see Projects →
