Mathematicians need to be able to communicate their work to non‑specialists. Helping the bank solve problems with mathematics is core to what I do. Frequently changing economic circumstances, such as upturns and downturns in the global economy necessitate the development of new mathematical models.

I am the head of credit model development at a large commercial bank. I'm responsible for the development of quantitative models to assess the credit risk that results from customer lending.

These models either predict the probability that a customer will not be able to pay back a loan (default) or predict the bank’s loss as a result of customer default. It's a very interesting job because you learn about global banking and finance and, as you can imagine, banking is centred on numbers. I use maths every day from calculating percentages, solving equations, producing data plots to using more advanced techniques that you learn at university.

I really enjoy what I do and like the opportunity to use maths to help and strengthen our businesses. I did a maths degree and then a PhD. I've found that a good understanding of Year 11 and 12 maths will broaden your opportunities and provide you with a solid basis for exploring different career paths as you enter the workforce. Banking is a good career choice as there are opportunities in different areas such as marketing, finance, information technology, accounting, human resources and legal to name a few.

Banking pays well and this is especially true if you are mathematically literate. The view that maths is not relevant is wrong. In banking, the ability to interpret data, develop models and articulate the models are sought after and hard to find skills.
