Ο Χρήστος Δουλκερίδης είναι Επίκουρος Καθηγητής στο Τμήμα Ψηφιακών Συστημάτων του Πανεπιστημίου Πειραιώς. Έχει λάβει υποτροφίες Marie-Curie και ERCIM “Allain Bensoussan” για μεταδιδακτορικές σπουδές στο Νορβηγικό Πολυτεχνείο Επιστημών και Τεχνολογίας το 2011 και 2009 αντίστοιχα. Πριν από αυτό, έλαβε διδακτορικό τίτλο σπουδών καθώς και μεταπτυχιακό τίτλο σπουδών από το Οικονομικό Πανεπιστήμιο Αθηνών το 2007 και το 2003 αντίστοιχα, και δίπλωμα ηλεκτρολόγου μηχανικού και μηχανικού ηλεκτρονικών υπολογιστών από το Εθνικό Μετσόβιο Πολυτεχνείο το 2001. Βραβεύθηκε ως δεύτερος νικητής του διαγωνισμού “Μιχάλης Δερτούζος” σχετικά με το “Ανθρώπινο Πρόσωπο της Πληροφορικής” στο 14ο παγκόσμιο συνέδριο World Congress on Information Technology (WCIT’04) το 2004. Επίσης, έχει λάβει το βραβείο καλύτερης εργασίας στο EuroVA’19, και ήταν νικητής του διαγωνισμού SemEval’17/Task4 σχετικά με την αναγνώριση συναισθήματος στο Twitter. Ήταν ο κύριος ερευνητής των ερευνητικών έργων CloudIX (Marie-Curie Post-Doc) και RoadRunner (ΓΓΕΤ/ΑΡΙΣΤΕΙΑ II), και συμμετέχει σε πολλά ευρωπαϊκά ερευνητικά έργα (datAcron, Track&Know, BigDataStack). Αυτό το διάστημα, είναι ο κύριος ερευνητής του ερευνητικού έργου CHOROLOGOS (ΓΓΕΤ/ΕΛΙΔΕΚ – Μέλη ΔΕΠ), το οποίο ασχολείται με την επεξεργασία σημασιολογικών χωρο-χρονικών-κειμενικών δεδομένων. Τα ερευνητικά του ενδιαφέροντα περιλαμβάνουν: μεγάλα δεδομένα, διαχείριση δεδομένων στο υπολογιστικό νέφος, επεξεργασία επερωτήσεων, διαχείριση δεδομένων σε δίκτυα ομότιμων κόμβων, κατανεμημένη εξόρυξη γνώσης, διαχείριση δεδομένων στον Παγκόσμιο Ιστό, κινητές και χωρικές βάσεις δεδομένων. Έχει δημοσιεύσει το ερευνητικό του έργο σε κορυφαία διεθνή περιοδικά (μεταξύ άλλων VLDB J, IEEE TKDE, IEEE J-SAC, ACM TKDD, Elsevier Information Systems, Springer DPD) και συνέδρια (μεταξύ άλλων ACM SIGMOD, VLDB, ICDE, EDBT, SSTD, PKDD, SIAM SDM) στις περιοχές διαχείρισης δεδομένων, εξόρυξη γνώσης και κατανεμημένων συστημάτων.
