Οι ερευνητικές του δραστηριότητες επικεντρώνονται στη θεωρία και προσομοιώσεις κβαντικού ελέγχου με στόχο τον γρήγορο και αποτελεσματικό έλεγχο των κβαντικών καταστάσεων σε συστήματα και υλικά κβαντικής τεχνολογίας όπως:
Κβαντικές τελείες
Συστήματα σπιν - κβαντικών ψηφίων
Συστήματα εξιτονίων - πολαριτονίων
Μποζονικές συζεύξεις Josephson
Οπτομηχανικά συστήματα
Κβαντικές θερμικές μηχανές
