Μελετάμε βασικούς μηχανισμούς που ρυθμίζουν την ανάπτυξη, τη μετάβαση της κυτταρικής μοίρας και την προσαρμογή σε καταπονήσεις σε πληθυσμούς δυναμικών βλαστικών κυττάρων. Η έρευνά μας στοχεύει στην κατανόηση του τρόπου με τον οποίο τα βλαστοκύτταρα αντιλαμβάνονται ενδογενή ή εξωγενή σινιάλα και πώς αυτά αλληλοσυνδέονται με δομικές και μηχανικές ιδιότητες των κυττάρων.
Εστιάζουμε κυρίως στην ομοιοστασία πρωτεϊνών και μορίων RNA δίνοντας έμφαση σε καταβολικές διεργασίες. Το κύριο βιολογικό μας σύστημα είναι το μοντέλο Arabidopsis. Είμαστε πεπειραμένοι σε ένα ευρύ φάσμα πειραματικών μεθόδων κυτταρικής βιολογίας, βιοχημείας, γενετικής και γονιδιωματικής επεξεργασίας. Επιπλέον, προσπαθούμε να επεκτείνουμε τις βασικές μας γνώσεις στη βελτίωση ειδών Brassicaceae σημαντικά για την οικολογία, τα τρόφιμα και το βιοντίζελ (π.χ. ελαιοκράμβη, Camelina).
