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 also 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, 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.
