Why study mathematics? Where can it take you?
Well, you could be the UK's Chief Scientific Adviser (Angela McLean, left), the Director GCHQ, the UK intelligence agency (Anne Keast-Butler, centre) or Chief Executive Citizens Advice UK (Clare Moriarty, right).
All studied maths at Oxford. Angela, who is now a professor of mathematical biology in Oxford studied at Somerville College; Anne who will take up her post in May is currently the Deputy Director General of MI5 and studied at Merton College; and Claire, who was Permanent Secretary of the Department for Environment, Food and Rural Affairs, studied at Balliol College.
