Οι ερευνητικές μας προσπάθειες εστιάζονται στη μελέτη των μοριακών μηχανισμών που διέπουν τη λειτουργία του νευρικού συστήματος καθώς και την παθογένεση νόσων που το αφορούν. Συγκεκριμένες κατευθύνσεις της έρευνας μας σχετίζονται με τους μηχανισμούς που είναι υπεύθυνοι για τον νεκρωτικό κυτταρικό θάνατο και φαινόμενα νευροεκφυλισμού, τους μηχανισμούς μνήμης και μάθησης, καθώς και τους μηχανισμούς γήρανσης. Επιπλέον, στο πλαίσιο των δραστηριοτήτων μας είναι και η ανάπτυξη νέων πειραματικών εργαλείων και μεθόδων για τη μελέτη του νευρικού συστήματος και της βιολογίας του κυττάρου.
