Rupal Patel became interested in economics during the 2007-8 financial crisis, when she was still at school. She soon started wondering why Woolworths was closing down, why the news was suddenly filled with GDP figures, and what all this had to do with the money in her pocket. Today, Rupal is an economist at the Bank of England, where she spends her days trying to make sure such crashes don't happen in future - and working out how to respond if they do.
