Είναι επί σειρά ετών επιστημονική συνεργάτιδα στο ΙΑΣΩ Παίδων, όπου ασχολείται με τη διατροφική υποστήριξη παιδιών και εφήβων, τόσο για την απώλεια βάρους, όσο και για τη διαχείριση κλινικών περιστατικών, όπως αλλεργίες, δυστροφία και άλλες διατροφικές ή ιατρικές καταστάσεις που απαιτούν εξειδικευμένη υποστήριξη. Παράλληλα, διαθέτει πολύχρονη εμπειρία στη διαχείριση ατόμων με νοσογόνο παχυσαρκία που έχουν υποβληθεί σε βαριατρική επέμβαση καθώς συνεργάζεται με ομάδα εξειδικευμένων χειρουργών, όπως ο Καθηγητής Χειρουργικής Λέανδρος Εμμανουήλ και η Χειρουργός Μαρία Νατούδη, συμβάλλοντας ουσιαστικά στη διατροφική τους αποκατάσταση και στη μακροχρόνια διατήρηση της απώλειας βάρους τους. 

Επίσης έχει ασχοληθεί εκτενώς με άτομα με Σακχαρώδη Διαβήτη Τύπου 1 και Τύπου 2, εγκυμονούσες με διαβήτη κύησης, καθώς και άτομα με μεταβολικές και ενδοκρινικές διαταραχές (δυσλιπιδαιμίες, παθολογικές καταστάσεις του θυρεοειδούς).

Η φιλοσοφία της βασίζεται στην εξατομικευμένη, ρεαλιστική και επιστημονικά τεκμηριωμένη προσέγγιση, με στόχο τη δημιουργία βιώσιμων συνηθειών και τη βελτίωση της σχέσης του ατόμου με τη διατροφή.

Οι συνεδρίες πραγματοποιούνται δια ζώσης ή online, με πλήρη αξιολόγηση και καθοδήγηση, πάντα με σεβασμό στις ανάγκες, το ιατρικό ιστορικό και τον τρόπο ζωής κάθε ατόμου.

Στο πλαίσιο των δια ζώσης συνεδριών, γίνεται χρήση σύγχρονου λιπομετρητή, για ακριβή ανάλυση της σύστασης σώματος (λιπώδης μάζα, μυϊκή μάζα, σωματικά υγρά), που επιτρέπει πιο στοχευμένη και αντικειμενική παρακολούθηση της προόδου.
