Yasin Gundesli, PhD student.

Yasin is a PhD student in forest ecophysiology at INRAE Silva, under the supervision of Emilie Joetzjer, Matthias Cuntz, and Oliver Brendel. His research investigates how the decoupling between photosynthesis and stomatal conductance affects carbon and water fluxes in beech trees (Fagus sylvatica), from the leaf to the whole-tree scale. Combining field experimentation and modelling, Yasin uses gas exchange measurements collected with instruments such as the LICOR 6800, both in greenhouse and forest settings. His work focuses on characterising stomatal and photosynthetic dynamics along the canopy light gradient and throughout the growing season. By fitting dynamic models to these measurements, he aims to quantify how stomatal–photosynthesis decoupling influences daily carbon assimilation and transpiration. This contributes to a better understanding of tree responses to light fluctuations and drought, and of their impact on water and carbon cycling in beech trees.
