ΣΥΜΜΕΤΟΧΗ ΣΕ ΕΡΕΥΝΗΤΙΚΑ ΠΡΟΓΡΑΜΜΑΤΑ

• Απο τις αρχές του 1984 μέχρι το τέλος του 1985 συμμετείχα σαν ερευνητής στην ερευνητική ομάδα του ΝΙΜΤΣ που σε συνεργασία μετο IMPERIAL CANCER RESEARCH FUND (ICRF)του Λονδίνου ασχολήθηκε ερευνητικά με τα μονοκλωνικά αντισώματα και τις εφαρμογές τους στη διάγνωση και θεραπεία του καρκίνου.
• Από 1/4/95-31/3/96 στο Νοσοκομείο Hammersmith του Λονδίνου ήμουν ο υπεύθυνος Ερευνητικού προγράμματος μεταμόσχευσης περιφερικών προγονικών κυττάρων του αίματος μετά από υψηλές δόσεις χημειοθεραπείας. Συμμετείχα επίσης την ίδια περίοδο στο Tumor Targeting Laboratory του Imperial Cancer Research Fund σε ερευνητικά προγράμματα με μονοκλωνικά αντισώματα στην διάγνωση και θεραπεία του καρκίνου.
• Από το 1988 έως σήμερα συμμετέχω σε δεκάδες ερευνητικά πρωτόκολλα σε αρκετά από τα οποία είμαι ο υπεύθυνος συντονιστής και τα αποτελέσματα των οποίων ανακοινώθηκαν ή/και δημοσιεύθηκαν σε διεθνή ή Ελληνικά έγκριτα περιοδικά και συνέδρια.
• Είμαι μέλος της Επιστημονικής Επιτροπής της Ελληνικής Συνεργαζόμενης Ογκολογικής Ομάδας (HeCoG), που ασχολείται με την διενέργεια κλινικών και εργαστηριακών μελετών. Η ομάδα αυτή έχει διενεργήσει μεγάλο αριθμό κλινικών μελετών φάσης Ι, ΙΙ και ΙΙΙ που αφορούν όλο το φάσμα των συμπαγών όγκων, τα αποτελέσματα των οποίων έχουν δημοσιευθεί σε έγκυρα διεθνή περιοδικά και έχουν ανακοινωθεί σε Διεθνή και Ελληνικά συνέδρια. Εκτός από μέλος της Επιστημονικής Επιτροπής της Επιστημονικής αυτής Ομάδας υπήρξα και υπεύθυνος σχεδιασμού, οργάνωσης και συντονιστής των πρωτοκόλλων που αφορούν τους καρκίνους του Γαστρεντερικού Συστήματος. Η Ελληνική Συνεργαζόμενη Ογκολογική Ομάδα βραβεύθηκε για το Επιστημονικό και Ερευνητικό της έργο από τηνΑκαδημία Αθηνών τον Δεκέμβριο του 2001.
• Συμμετείχα ως ερευνητής σε πολλές Διεθνείς πολυκεντρικές μελέτες με άδεια του ΕΟΦ, της Επιστημονικής επιτροπής και του Δ.Σ. του Νοσοκομείου μου.
• Την παρούσα περίοδο συμμετέχω ως υπεύθυνος ερευνητής σε οκτώ διεθνείς μελέτες.
