About

I am the coordinator of the Maths Learning Centre at the University of Adelaide. I have a PhD in finite geometry and a Graduate Diploma in Education. I help thousands of students every year to understand the maths involved in their courses. If you want to know more about what I think about maths and its education, check out my blog.
