Ο κος Χατζηγεωργίου γεννήθηκε στο Παλαιομέτοχο της επαρχίας Λευκωσίας και αποφοίτησε από το γυμνάσιο Κύκκου Αρρένων. Σπούδασε στην Ιατρική Σχολή του Εθνικού & Καποδιστριακού Πανεπιστημίου Αθηνών από το οποίο αναγορεύθηκε Διδάκτορας Iατρικής. Ειδικεύθηκε στη Νευρολογία στο Νοσοκομείο του Ελληνικού Ερυθρού Σταυρού στην Αθήνα. Μετεκπαιδεύθηκε σε θέματα Νευρογενετικής στο Πανεπιστήμιο του Μιλάνου και στο Πανεπιστήμιο Columbia της Νέας Υόρκης.  Εκλέχθηκε διαδοχικά σε όλες τις ακαδημαϊκές βαθμίδες και υπηρέτησε σαν Καθηγητής Νευρολογίας, Διευθυντής της Πανεπιστημιακής Νευρολογικής Κλινικής και Πρόεδρος του Τμήματος Ιατρικής της Σχολής Επιστημών Υγείας του Πανεπιστημίου Θεσσαλίας. Πριν από την εκλογή του στο Πανεπιστήμιο Κύπρου είχε εκλεγεί Καθηγητής στην Ιατρική Σχολή του Εθνικού & Καποδιστριακού Πανεπιστημίου Αθηνών θέση την οποία δεν αποδέχθηκε μετά την εκλογή του στο Πανεπιστήμιο Κύπρου. 

Διετέλεσε Διευθυντής της Μονάδας Νευροεπιστημών και του ερευνητικού και διαγνωστικού Εργαστηρίου Νευρογενετικής του Πανεπιστημίου Θεσσαλίας. Είναι ιδρυτικό μέλος της Ελληνικής Ακαδημίας Νευροανοσολογίας και της Ομάδας μελέτης του ρόλου της μεσογειακής διατροφής στα νευροεκφυλιστικά νοσήματα (The Hellenic Longitudinal Investigation of Aging and Diet-HELIAD). Συμμετέχει σαν κύριος ερευνητής σε διεθνείς ομάδες μελέτης νευρολογικών νοσημάτων συμπεριλαμβανομένων του Genetic Epidemiology of Parkinson's Disease consortium (GEO-PD), του International Stroke Thrombolysis Register (SITS-ISTR) και του International Multiple Sclerosis Genetic Consortium (IMSGC). Διετέλεσε αντιπρόεδρος του European Restless Legs Syndrome Study Group (EURLSSG).Η αυτόνομη ερευνητική δραστηριότητα αλλά και οι διεθνείς συνεργασίες του κου Χατζηγεωργίου απέδωσαν πέραν των 240 PubMed δημοσιεύσεων (https://www.ncbi.nlm.nih.gov/m/pubmed/?term=hadjigeorgiou+g) με Scopus h-index > 40. Έχει δημοσιεύσει ερευνητικές μελέτες σε σημαντικά επιστημονικά περιοδικά συμπεριλαμβανομένων των Cell, Nature Commun, Nature Genetics, JAMA, Lancet, Annals of Neurology και Neurology.
