She has taken part in excavations in Greece and abroad (Syria, Turkey), has presented scientific communications in over 50 national and international conferences and has written more than 30 studies related to her scientific interests: Late Antiquity (evolution of urban centers, economy, trade with an emphasis on amphorae and marble), Byzantine seals, prosopography and iconography. She is a collaborator in international research projects and has served as Principal Investigator and Academic Advisor in funded projects hosted by the Academy of Athens. In November 2013 her research proposal on Byzantine Asia Minor was one of 180 research projects (out of a total of 1622 submitted proposals) to receive funding by the "ARISTEIA II" programme of the National Strategic Reference Framework, NSRF 2007-2013, with the amount of 200,000 euros.
