Mary has a passion for teaching mathematics based on the firm belief that all students can be motivated and supported to achieve and need not be left behind due to special needs, interruptions to study, family circumstances, or even a past history of low success. She makes it her mission to explain the uses of mathematics in a wide variety of fields, and is well known for presenting interesting lectures and courses that challenge students to think. She currently teaches quantitative literacy as an elective subject called "Arguments, Evidence and Intuition", available to all UTS students, and also is the Director of the UTS Mathematics and Science Study Support Centre.
