My main research interest is how different languages express mathematical ideas. I am particularly interested in mathematical expression in non-Indo-European languages, including languages that have not formally been used in schooling, such as many Australian Indigenous languages. I am also interested in policies and practices associated with the use of different languages in mathematics education, with a focus on Indigenous education. I have researched in these areas in both Australia and Papua New Guinea. I did postdoctoral research at the University of Melbourne (2016-2018) and Umeå University, Sweden (2014-2016).

I lecture in mathematics education with expertise in the early acquisition of mathematics and cultural contexts of mathematics. I coordinate the Growing Our Own program, a partnership with Catholic Education NT that delivers community-based teacher training to Indigenous assistant teachers. I have also provided professional development to elementary school teachers in various provinces of Papua New Guinea. I am a qualified and registered primary school teacher and have taught in various schools in Darwin and the Top End.

I am active in both national and international research communities, an affiliate of the ARC Centre of Excellence for the Dynamics of Language, the Research Unit for Indigenous Language at the University of Melbourne and the Umeå Mathematics Education Research Centre. I am a member of the Mathematics Education Research Group of Australasia, and I was Treasurer of the International Group for the Psychology of Education from 2016-2018.
