Holly Krieger works in dynamical systems theory, in particular on chaotic systems. Some of her greatest mathematical moments have come from teaching students.

Julia Gog is a mathematical biologist, helping to understand how infectious diseases spread. One of her favourite eureka moments came while she was playing a computer game.

Nilanjana Datta works in quantum information theory. She loves how mathematics can describe nature simply and elegantly.

Anne-Christine Davis is a professor of theoretical physics whose long career has seen attitudes towards women change for the better. She had to put up with quite a lot at the start.

Carola-Bibiane Schönlieb uses mathematics to process and analyse images. She loves the collaborative nature of maths.

Natalia Berloff is a professor of applied mathematics. It was a problem in network theory that lured her into the exciting world of maths when she was ten years old.
