When Kathleen Friel was young, she was diagnosed with cerebral palsy, and a doctor told her parents all the things she'd never be able to do.

They left his office for good and found a new doctor.

As Kathleen grew up, she found her own methods to tackle tricky tasks and make her way through the world. After becoming fascinated by science, she went on to earn a PhD, investigating how injured brains can build new connections. She now runs her own lab, developing new techniques to help others with cerebral palsy.

This is the incredible story of how a determined scientist rewrote the rules and followed her dreams.
