Originally from Virginia in the US, Cassie received her PhD from the University of Glasgow in 2012 for her thesis on code-switching and language maintenance in a Gaelic-speaking family on the Isle of Skye, Scotland. From 2012-2016, Cassie was a research fellow for Soillse, the interuniversity Gaelic language research network, for the University of the Highlands and Islands. Part of this fellowship was spent at Lews Castle College on the Isle of Lewis and between 2014-2015, Cassie also held a fellowship at the Institute for the Advanced Studies in the Humanities at the University of Edinburgh, during which time she completed her monograph Family Language Policy: Maintaining an Endangered Language in the Home (Palgrave, 2016). Other publications include articles in the Journal of Pragmatics; Journal of Multilingual and Multicultural Development; Current Issues in Language Planning; Language, Culture and Curriculum; and the International Journal of the Sociology of Language. Cassie is currently at the University of Limerick with a Government of Ireland Postdoctoral Fellowship awarded by the Irish Research Council to conduct a comparative study of Family Language Policy (FLP) in Scotland and Ireland.
