ABOUT ME

 

Biography

 

Education is my vocation - a voice, calling from within me since I was young.  In my mind, education forms a place where my personal passion intersects with the world's deep needs. Education is what I've been doing with my life that makes a personal difference and what will form part of my legacy - something that can be looked back on in later years to see the meaningful impact on the world.

I am Professor of Mathematics and Mathematics Education at UNSW. I am also an Honorary Professor of STEM & Digital Education at UQ (Brisbane). My significant and innovative contributions to the student experience have positively impacted millions of people around the world by meeting the challenges of scale, flexibility and personalized learning. I am probably best known for leading Australia’s earliest YouTube channel dedicated to learning mathematics, now in its thirteenth year of operation. 

A teacher at heart, the quality and impact of my work on the student experience has been recognized at national and international levels, through fellowships and prestigious awards for educational excellence, including diversity and inclusion. As Associate Dean (Education), I was responsible for improving the quality, recognition and transparency of the student experience across ~600 courses, 30 programs and ~10,000 students within The Faculty of Science at UNSW. This includes leading TEQSA re-registrations and chairing program reviews. As VP (Education) at the Australian Maths Society, I lead a national portfolio that promotes the learning and teaching of STEM, including research training.

I am proud to collaborate with key partners within the education industry, ensuring continuous improvement and collaborative advantage therein.  I promote innovation in education through public engagement and thought leadership at national and international levels as an expert and public figure.
