I am a lecturer in mathematics education at the University of Queensland. My research area is mathematics and statistics education, and teacher professional development. I study how to effectively support mathematics teachers' professional development so that students have opportunities to learn meaningful mathematics. To this end, I am interested in both classroom instructional practices in which teachers build on student reasoning to provide all students access to significant mathematical ideas, and in the design of environments that support teachers' development of such practices.
I completed a Magister degree in mathematics at Comenius University in Slovakia and a PhD in mathematics education at Vanderbilt University in the USA. I have taught middle-years mathematics for 3 years and lectured in mathematics and mathematics education at Comenius, Vanderbilt, and University of California, Santa Cruz.
