Cris is a senior lecturer in early childhood and primary mathematics education at CDU. She coordinates the Remote Aboriginal Teacher Education Program that delivers community-based teacher training to Indigenous assistant teachers in remote communities. Her main research interest is how different languages express mathematical ideas, non-Indo-European languages that have not formally been used in schooling, such as many Australian Indigenous languages. Her current focus is on developing a framework for developing mathematics registers in Australian Indigenous languages. She is also interested in policies and practices associated with the use of different languages in mathematics education, with a focus on Indigenous education and has researched in these areas in both Australia and Papua New Guinea. She did postdoctoral research at the University of Melbourne (2016-2018) and Umeå University, Sweden (2014-2016).
