Επιμελητής στο Τμήμα Γενικής, Λαπαροσκοπικής, Ογκολογικής και Ρομποτικής Χειρουργικής στο Ιατρικό Κέντρο Αθηνών

Σπούδασε στην Ιατρική Σχολή του Πανεπιστημίου Αθηνών και μετά το πέρας των σπουδών του μετέβη απευθείας στο εξωτερικό και πραγματοποίησε το σύνολο της ειδικότητας της Χειρουργικής σε ένα από τα πλέον ιστορικά και ονομαστά Πανεπιστήμια της Γερμανίας, την Πανεπιστημιακή Κλινική του «Philipps-University Marburg», που αποτελεί κορυφαίο κέντρο αναφοράς στη χειρουργική ενδοκρινών αδένων και νευροενδοκρινών όγκων. Το έντονο και διαρκώς αυξανόμενο επιστημονικό και ακαδημαϊκό ενδιαφέρον του, τον οδήγησε στην ολοκλήρωση της διδακτορικής του διατριβής το 2019 με θέμα «Evaluation of the safety of early drain removal after partial pancreaticoduodenectomy».

Μετά την απόκτηση της ειδικότητας της Γενικής και Σπλαχνικής Χειρουργικής, εργάστηκε αρχικά ως επιμελητής Β και στη συνέχεια ως επιμελητής Α και σε άλλες ονομαστές κλινικές της Γερμανίας, συμμετέχοντας και διενεργώντας και ο ίδιος πληθώρα επεμβάσεων που καλύπτουν όλο το φάσμα της γενικής χειρουργικής.

Το πλούσιο συγγραφικό του έργο και η απρόσκοπτη ενασχόληση του με την εκπαίδευση των φοιτητών της Πανεπιστημιακής Κλινικής Marburg άνοιξαν το δρόμο για την αναγόρευσή του σε Αναπληρωτή Καθηγητή (PD Dr. med.) στο Πανεπιστήμιο «Philipps-University Marburg». Συνεχίζει με υπευθυνότητα και αμείωτο ενθουσιασμό το ακαδημαϊκό του έργο στην Πανεπιστημιακή Κλινική Marburg, συμμετέχοντας στη διδασκαλία και την επίβλεψη διδακτορικών διατριβών των φοιτητών του Πανεπιστημίου.
