Ricercatore in Ecologia Forestale (AGR/05) presso il Dipartimento Territorio e Sistemi Agro-Forestali (Università degli Studi di Padova) a partire dal 22 dicembre 2011. Durante la formazione post-laurea (in Scienze Forestali ed Ambientali – Università degli Studi di Padova) ha approfondito i temi dell’eco-fisiologia vegetale con particolare attenzione alle relazioni idriche ed alle caratteristiche anatomico-funzionali dello xilema legate all’ottimizzazione del sistema di trasporto dell’acqua. Ha svolto in diverse occasioni attività di ricerca presso istituti esteri per affinare metodologie di ricerca e promuovere collaborazioni scientifiche. Ha pubblicato le proprie ricerche su prestigiose riviste internazionali.

Researcher in Forest Ecology (Dept. Territorio e Sistemi Agro-Forestali – Università degli Studi di Padova) since the 22nd of December 2011. After the Degree in Forestry and Environmental Sciences (Università degli Studi di Padova) his scientific formation focused mainly on plant ecophysiology, with particular attention to water relations and the anatomical features of the xylem system related to the optimization of water transport. He carried out research activities at foreign institutes to acquire new research methodologies and to promote scientific collaborations. He published his researches in prestigious international journals.
