Scientific work
As a plant ecophysiologist, I study abiotic and biotic stresses and responses of trees growing in harsh environments, with a focus on mountain trees and mangroves. Main interests are plant hydraulics, drought and frost effects, and the underlying structure-function relationships.
In 2014, I obtained a Master's degree in Biology from the University of Trieste, Italy. In the same year, I started a PhD in plant ecophysiology in the lab of Prof. Stefan Mayr (University of Innsbruck, Austria), which I obtained in 2018. Since then, I conducted numerous studies on the hydraulics of alpine tree species, focusing on winter embolism and recovery, xylem sap composition, xylem anatomy, and hydraulic safety. I also spent two years as a postdoctoral researcher in the laboratory of Prof. Brendan Choat (Western Sydney University, Australia), studying the effects of natural drought on the hydraulics of Australian trees and the physiological adaptations of mangroves.
I am currently back in Innsbruck, where I am investigating the vulnerability of tree seedlings to drought and frost.
