She served for ten years as director of the Hellenic Institute at Royal Holloway, University of London, transforming it into a centre for interdisciplinary research into Greek and Byzantine history.
Discouraged by the rising anti-Greek sentiment in Istanbul, she moved to England in 1950 to pursue a degree in Literae humaniores at St Anne's College, Oxford, from which she graduated in 1955.
[2] That year she began a BLitt at Royal Holloway under Professor Joan Hussey, writing on Emperor Manuel II Palaeologus and his policy towards the Ottomans.
She also produced a number of volumes in co-operation with other scholars, including The Letter of the Three Patriarchs to Emperor Theophilos (with Joseph Munitiz and others, 1997), The Greek Islands and the Sea (with Charalambos Dendrinos and Jonathan Harris, 2004), ‘Sweet Land …’: Lectures on the History and Culture of Cyprus (with Charalambos Dendrinos, 2006), and a Catalogue of the Greek Manuscripts in Lambeth Palace Library (with John Barron and others, 2006).
Her funeral took place on 1 November 2008 at St Sophia's Cathedral, London, attended by representatives of Greece and the Republic of Cyprus as well as her former students, colleagues and friends.
