Προσωπικό Προφίλ

Ο Δρ Γιάννης Διαλυνάς έλαβε τον τίτλο του Πολιτικού Μηχανικού από το Εθνικό Μετσόβιο Πολυτεχνείο (2011), μεταπτυχιακό τίτλο σπουδών (M.Sc.) από τη Σχολή Πολιτικών Μηχ. και Μηχ. Περιβάλλοντος του Georgia Institute of Technology (Ατλάντα, Τζόρτζια, ΗΠΑ) το 2013 και τον τίτλο του Διδάκτορα (Ph.D.) στο αντικείμενο της Υδρολογίας και Μηχανικής Υδάτινων Πόρων από την ίδια Σχολή το 2017. Εργάσθηκε ως μεταδιδακτορικός ερευνητής στο Georgia Tech και στο Τμήμα Πολιτικών Μηχ. και Μηχ. Περιβάλλοντος του University of California, Irvine (Καλιφόρνια, ΗΠΑ) μέχρι το 2018, όταν και ανέλαβε καθήκοντα Λέκτορα στο Τμήμα Πολιτικών Μηχ. και Μηχ. Περιβάλλοντος του Πανεπιστημίου Κύπρου.

Η έρευνά του εστιάζει σε σημαντικά προβλήματα επιστημονικού και κοινωνικο-οικονομικού ενδιαφέροντος, όπως η παγκόσμια κλιματική αλλαγή, οι φυσικές καταστροφές και η βιωσιμότητα των υδάτινων πόρων. Το 2016 βραβεύθηκε από τη NASA με την Υποτροφία Γης και Διαστημικής για την έρευνά του πάνω στην επιρροή υδρολογικών διεργασιών στην ανταλλαγή Διοξειδίου του Άνθρακα μεταξύ εδάφους και ατμόσφαιρας. Είναι Μέλος της Τεχνικής Επιτροπής Οικολογίας-Υδρολογίας της Αμερικάνικής Γεωφυσικής Ένωσης (AGU) και πρόσφατα συνέβαλε ως συγγραφέας στην 2η Αξιολόγηση Κύκλου του Άνθρακα της Β. Αμερικής του Επιστημονικού Προγράμματος Κλιματικής Αλλαγής των ΗΠΑ (SOCCR2, 2018), η οποία περιλαμβάνει σημαντικά επιστημονικά ευρήματα σχετικά με επιπτώσεις κλιματικής αλλαγής στον Κύκλο του Άνθρακα και αποτελεί βάση της 4ης Εθνικής Κλιματικής Αξιολόγησης της Κυβέρνησης των ΗΠΑ (NCA4).
