Daphne Koller was a precociously clever child. She completed her first degree – a double major in mathematics and computer science – when she was just 17 and went on to become a distinguished Professor at Stanford University in California. But before long she’d given up this comfortable academic position to create the biggest online education platform in the world. In 2018, she founded the drug discovery company Insitro hoping to create a space where data scientists and molecular biologists could work together as equals.

Daphne tells Jim Al-Khalili how a single question from her supervisor nudged her to use her considerable mathematical ability to do something useful and why she believes the time is right for artificial intelligence to discover new medicines. Producer: Anna Buckley
