Prior to her Cambridge appointment in 2004 Prof. Ioanna Sitaridou worked as a postdoctoral researcher at the Research Centre on Multilingualism at the University of Hamburg, investigating word order in Old Romance and the licensing/loss of null subjects in the history of French and Occitan (2002-2005), with Prof. Dr. Dr. h.c. Jürgen Meisel.

She received her PhD in Romance linguistics at the University of Manchester (2002) under the supervision of Prof. Nigel Vincent. She holds an MA in Linguistics from University College London (UCL) (1998). She also holds a BA in French Philology from Aristotle University of Thessaloniki (1997), part of which was spent under the Erasmus scheme at the University of Lisbon (1997) studying Portuguese and Romance linguistics with Prof. Ana Maria Martins.

Her main areas of research are comparative and diachronic syntax of the Romance languages, in particular 13th Century Spanish, as well as dialectal Spanish; and dialectal Greek, especially Pontic Greek. The areas in which she carries out research are: the relationship between syntactic change and acquisition, language contact, micro-variation and change, heritage languages and change, and phylogenies.

Her research has been funded thrice by British Academy and several times by the Cambridge Humanities Research Grants Scheme 2014; in 2019 she won a competitive CAPES grant at the UFB in Salvador, Brazil for Romance syntax; research buyout from ISWOC at Oslo (2012) for Old Ibero-Romance syntax; and a CRASSH fellowship (2008) for a project on Old Romance word order.

She has published many papers in Glossa, Lingua, Diachronica, Natural Language and Linguistic Theory, among others, and her book on Word Order in Old Ibero-Romance (with Prof. Montserrat Batllori) will appear by CUP in 2022. For her research on Romeyka she was awarded the Stanley J. Seeger Visiting Research Fellowship in Hellenic Studies by Princeton University in Spring 2011; a Research Fellowship at the Center for Hellenic Studies at Harvard University in Winter 2015; and the Chaire internationale 2020 du Labex EFL. Her work on Romeyka has featured in national and international media (the Today programme in BBC Radio 4, The Independent, Der Spiegel, Sabah, etc.). She uses this research and the resulting publicity to educate on bilingualism, promote linguistic self-esteem, especially for female speakers in remote areas of Turkey.

Prof. Sitaridou welcomes inquiries from potential MPhil and PhD students with research interests relevant to her interests.
