From June 1975 until May 1979 she worked at the Research Centre for the Study of Modern Greek History of the Academy of Athens. Under the supervision of the Director Eleftherios Prevelakis she compiled a descriptive list of documents of the correspondence of the Foreign Office with the British Embassy in Constantinople and the British Consular authorities in the Ottoman Empire, which covers the period 1820-1833. The work was completed in 2005 with the publication of the Correspondence between the Foreign Office and the British Embassy and Consulates in the Ottoman Empire 1821-1832. A Descriptive List. Compiled by Eleftherios Prevelakis and Helen Gardikas- Katsiadakis Volume 1, Athens 2003, Volume 2, Athens 2005. The section of the series selected, volumes 97-221, covers the period 1820-1833 and is of particular interest for the Greek history, because the largest part of the material concerns the Greek Revolution and events related to it. This material highlights the leading role of Great Britain mainly in the political, but also in the economic and strategic developments related to one of the most crucial phases of the Eastern Question. It also sheds light on important aspects of internal and international developements of the Greek Revolution and of the policy of the Porte toward the Greek rebels and the other provinces of Empire. Finally, it provides valuable information on the social conditions of the period. Important details emerge respecting not only the extensively researched political aspects of the Eastern Question, but also respecting social, technological and economic issues, information on institutions and mentalities etc.

Lately, she devotes most of her time to initiatives for the promotion of digital research infrastructure for the humanities. However, her continuing research interests involve aspects of early 19th century political history (Greek Revolution) and pre- World War I political and diplomatic history. Her particular areas of research focus on the suppression of slavery and slave trade during the Greek Revolution and on her long term project, which is the preparation of a biography of Ioannis Valaoritis. Material for both these subjects will soon become available on this web page.
